Why does my Mac display look too yellow?
A yellow or orange tint on a Mac display almost always has one of three causes: Night Shift set to maximum warmth, True Tone responding to warm ambient lighting, or a third-party display app with high warmth settings. Here is how each one works and how to fix it.
Night Shift set to maximum warmth
This is the most common cause by a significant margin. Night Shift shifts the display's colour temperature towards warmer (lower Kelvin) values. At the More Warm end of the slider, macOS pushes the display to approximately 3000K - a distinctly orange-yellow tone that can make white backgrounds look cream or amber, particularly noticeable in documents, spreadsheets, and web pages with white backgrounds.
The fix is straightforward. Open System Settings > Displays > Night Shift and move the colour temperature slider towards Less Warm. A midpoint setting gives you meaningful blue-light reduction without the pronounced yellow cast. If you do not need Night Shift at all during the day, turn it off entirely - toggle the Schedule dropdown to Off.
Night Shift's default schedule is Sunset to Sunrise, which means it turns on automatically at sunset whether you set it manually or not. If your display turns yellow every evening, this is why.
True Tone adapting to warm ambient light
True Tone uses the ambient light sensors in your Mac to adapt the display's colour temperature to match the surrounding environment. This is genuinely useful during the day, but it can produce a pronounced yellow cast when you are working under warm incandescent or halogen bulbs. Bulbs with a colour temperature of 2700–3000K are significantly warmer than daylight, and True Tone will push the display towards that warmth to reduce the perceived mismatch between screen and environment.
If your display looks yellow specifically in warm artificial lighting - and returns to normal under daylight or cool LED light - True Tone is the likely cause. To disable it, open System Settings > Displays and uncheck the True Tone checkbox. The display will immediately revert to its fixed colour profile.
Whether to leave True Tone on or off is a matter of preference. For casual use and reading, the ambient adaptation is beneficial. For colour-sensitive work - photo editing, graphic design, video grading - disable True Tone so the display maintains a consistent, calibrated colour temperature.
Third-party display apps
Apps like f.lux, Solace, and similar tools apply their own colour temperature overlays, which operate on top of Night Shift. If you have any of these apps installed with high warmth settings, they will compound Night Shift's effect. Check the menu bar for any active display apps and reduce their warmth level or disable them temporarily to identify whether they are the source.
The fix when using Solace is to open the app from the menu bar and reduce the warmth slider for the current time period. Solace applies precise warmth values and shows you the current Kelvin target, making it easy to dial back to a comfortable level.
Why does my Mac display look too blue or cold?
A blue or cold-looking display is the opposite problem. Rather than too much warmth, the display is showing its default uncalibrated colour temperature, which most people perceive as noticeably cool or blue - particularly in the evening when the surrounding environment is lit by warm artificial light.
Night Shift is turned off
When Night Shift is disabled, most Mac displays revert to approximately 6500K - the standard daylight colour temperature used as the factory default for most monitors. Under direct sunlight or in a bright daylit room, 6500K looks neutral. In the evening under warm artificial lighting, the same 6500K display appears noticeably blue-white by contrast, because the surrounding environment is much warmer.
This is not a fault with the display - it is working as calibrated. The issue is the mismatch between the display's fixed colour temperature and the warmer ambient light. Enabling Night Shift and setting it to a moderate warmth level bridges this gap. Open System Settings > Displays > Night Shift, set the schedule to Sunset to Sunrise, and move the slider to a comfortable warmth level.
Night Shift schedule reset after a macOS update
macOS updates occasionally reset display preferences, including Night Shift schedules. If your display started looking blue after an update, check System Settings > Displays > Night Shift to confirm the schedule is still set. It may have reverted to Off or had its warmth level reset to the cooler end of the slider.
New display or new Mac
A brand-new display or Mac will be factory-set to 6500K with no Night Shift active. Coming from an older Mac where Night Shift was enabled, the new display can appear strikingly blue by comparison. This is normal - simply enable Night Shift and set your preferred warmth level, or configure a dedicated schedule with Solace.

How do you calibrate Mac display colour temperature?
If your display has a persistent colour cast - yellow or blue - even with Night Shift and True Tone disabled, the issue may be with the display's colour profile rather than any software overlay. macOS includes a built-in calibration tool that can correct this.
Using the Display Calibrator Assistant
The Display Calibrator Assistant is a step-by-step guided tool built into macOS that creates a custom ICC colour profile for your display. To access it, open System Settings > Displays > Color Profile, then click Calibrate… at the bottom of the colour profile list.
The assistant walks you through a series of visual tests to determine how your display is rendering colours. At the end, it generates a custom colour profile that compensates for any persistent tint or colour cast. This profile is saved and applied automatically every time you use the display.
The Display Calibrator is particularly useful for:
- External monitors with inherent colour cast issues (common with budget panels)
- Older displays where colour accuracy has shifted over time
- Displays with no hardware calibration profile available
Hardware calibration for accurate results
The built-in Display Calibrator Assistant uses visual estimation, which is inherently subjective. For professional colour accuracy - photography, video, print production - a hardware colorimeter produces significantly better results. Widely used options include the X-Rite i1Display and Datacolor SpyderX, both of which come with macOS-compatible software that automates the calibration process and generates precise ICC profiles.
For everyday use, the built-in assistant is sufficient. For creative professionals working with colour-critical content, a hardware colorimeter pays for itself in reduced colour correction time. See How to Calibrate Your Mac Display for Eye Comfort for a full walkthrough.
How do Night Shift and True Tone interact?
Night Shift and True Tone both affect the display's colour temperature, and they operate simultaneously. Understanding how they interact helps you avoid the compounding effect that produces an extremely yellow display in warm-lit rooms.
Night Shift applies a fixed colour temperature adjustment on a schedule - it shifts the display to a warmer (lower Kelvin) value at a set time, regardless of the ambient environment. The warmth level is determined by the slider in System Settings.
True Tone applies a dynamic adjustment based on the ambient light sensors. It reads the colour temperature of the light in the room and shifts the display to match. In a warm room (incandescent bulbs at 2700K), True Tone shifts the display warmer. In a cool room (daylight at 6500K), True Tone makes little adjustment.
When both are active, their effects combine. In a warm room at night with Night Shift at maximum and True Tone active, the display can reach an extremely warm, orange-tinted state that makes content genuinely difficult to read. The problem is not either setting individually - it is the unintended stacking when both are running at high intensity simultaneously.
The recommended approach is to use True Tone as a constant ambient adaptation layer, and set Night Shift to a moderate warmth level rather than maximum. This gives you the ambient-matching benefit of True Tone plus meaningful blue-light reduction from Night Shift, without the extreme yellow cast caused by running both at full intensity.
Alternatively, use Solace to replace Night Shift entirely. Solace gives you precise, scheduled warmth control and makes it easy to set a level that works well alongside True Tone. See How to Use True Tone and Night Shift Together on Mac for detailed guidance on pairing the two settings effectively.
If your display looks orange right now, the fastest fix is to open System Settings > Displays > Night Shift and move the slider left towards Less Warm. A mid-slider position - roughly 4000K - removes the orange cast while still providing blue-light reduction.
What is the best colour temperature for a Mac display?
There is no single answer, because the right colour temperature depends on the time of day, your ambient lighting, and what you are using the Mac for. Here are the practical ranges for different contexts.
| Time / Use | Recommended Kelvin | Notes |
|---|---|---|
| Daytime work | 5500–6500K | Close to daylight; accurate colour rendering for design, photo editing, and document work |
| Late afternoon | 4500–5500K | Slightly warmer than daylight; reduces blue light stimulation as the day winds down |
| Evening work | 3500–4500K | Meaningfully warmer; minimises sleep-disrupting blue light while maintaining readability |
| Night use | 3000–3500K | Practical maximum warmth; warmer than this and colour accuracy is too compromised for most tasks |
Night Shift provides a rough approximation of this: its Less Warm end corresponds to approximately 4000K and its More Warm end to approximately 3000K. Apple does not publish the exact Kelvin values that Night Shift maps to its slider positions.
Solace addresses this limitation directly. It lets you set precise colour temperature schedules in Kelvin for different times of day, so you can have your morning display at 6000K, afternoon at 4500K, and evening at 3500K - each activating automatically without any manual adjustment.
For colour-critical work, always disable any colour temperature tools (Night Shift, True Tone, Solace) and use a display calibrated to D65 (6500K) with a hardware colorimeter. Warm display tints compromise colour accuracy, so creative professionals should use these tools outside of colour-critical sessions. See How to Reduce Blue Light on Mac Beyond Night Shift for more on display settings and colour accuracy.
How does Solace help you dial in the right warmth?
Solace is a macOS menu bar app that replaces the manual Night Shift workflow with a precise, automated daily schedule. Instead of toggling Night Shift on and off or adjusting the slider by feel, you configure exact warmth levels for each part of the day and Solace handles the rest.
Precise warmth scheduling
Solace lets you set different warmth levels for morning, afternoon, and evening. A typical setup might look like: no adjustment until midday, 4500K from early afternoon to sunset, then 3500K for the evening. Each transition happens automatically at the configured time, every day, without any manual input.
This solves the two most common colour temperature problems. For users whose display goes too yellow: Solace gives you a precise Kelvin value to target, rather than the Night Shift slider which provides no numerical feedback. For users whose display looks too blue in the evenings: Solace ensures the warmth setting activates reliably every day, even after a macOS update that might have reset Night Shift.
Works independently of Night Shift
Solace operates as a separate layer from Night Shift. You can disable Night Shift entirely and let Solace handle all colour temperature control, which eliminates the risk of both tools running simultaneously and stacking their effects. This is the cleanest configuration: one tool, one schedule, no accidental compounding.
Combined dark mode and warmth scheduling
Solace also automates dark mode switching. You can configure dark mode to activate at the same time as the evening warmth increase, so the display shifts both warmer and to dark mode simultaneously at sunset. The two settings complement each other: warm colour temperature reduces blue light stimulation, dark mode reduces total screen luminance. Running both in the evening produces the most comfortable display environment for low-light use.
Solace costs $4.99 as a one-time purchase. There is no subscription, no data collection, and no telemetry. It runs on macOS Sequoia and later.

Frequently asked questions
Why is my Mac screen orange?
Your Mac screen looks orange because Night Shift is set to maximum warmth, which shifts the display to approximately 3000K - a distinctly orange/amber tone. Open System Settings > Displays > Night Shift and move the colour temperature slider towards Less Warm, or turn Night Shift off entirely. True Tone in a warm-lit room can compound the effect, so if the orange cast is severe, try disabling True Tone as well.
How do I fix Mac display colour temperature?
For a yellow or orange display: reduce Night Shift warmth in System Settings > Displays > Night Shift, or disable True Tone if warm ambient lighting is the cause. For a blue or cold display: enable Night Shift and set a moderate warmth level, or use Solace for automated evening warmth. For a persistent tint unrelated to these settings, use the Display Calibrator Assistant at System Settings > Displays > Color Profile > Calibrate to create a corrective ICC profile.
What is the ideal colour temperature for a Mac?
For daytime work, 5500–6500K (close to daylight) gives accurate colour rendering. For evening work, 3500–4500K reduces blue light stimulation for more comfortable use before sleep. For night use, 3000–3500K is the practical minimum - warmer than this compromises colour accuracy significantly. Night Shift's More Warm setting is approximately 3000K; Less Warm is approximately 4000K. Apple does not publish exact values.
Can I use Night Shift and True Tone at the same time?
Yes, but they stack. Night Shift warms the display to a fixed colour temperature on a schedule, while True Tone adapts it dynamically to the ambient light. In a warm-lit room with both at maximum, the display can become very orange. The recommended approach is to leave True Tone on at all times and set Night Shift to a moderate warmth level - not maximum - so the combined effect stays within a comfortable range. See How to Use True Tone and Night Shift Together on Mac for detailed guidance.
Does Solace replace Night Shift?
Solace works independently of Night Shift and can replace it entirely. You can disable Night Shift and use Solace to handle all colour temperature scheduling, giving you precise Kelvin control rather than Night Shift's approximate slider. Solace also lets you set different warmth levels for different times of day (morning, afternoon, evening), which Night Shift cannot do - it only offers a single warmth level that activates at a set time.
