What "change color" means and where to find it

Color settings let you adjust how your screen displays colors, how bright it is, and sometimes what colors appear in your interface. On most devices, you are not actually changing the hardware — you are telling the operating system how to process the colors it sends to your screen.

The reason you might want to do this: your screen might look too yellow or too blue, text might be hard to read, or you might want a darker interface to reduce eye strain at night. Some people change color settings because they have color blindness and need certain colors adjusted to see them better.

Where you find these settings depends on whether you are using Windows, Mac, Android, or iOS. Each one stores color controls in a different place, and each one calls them by slightly different names.

Key Takeaways

  • On Windows, color settings live in Settings > System > Display, where you can adjust brightness, contrast, and color temperature.
  • On Mac, go to System Settings > Displays to change brightness and color profile, or System Settings > Accessibility > Display for color filters.
  • On Android phones, Settings > Display usually has brightness and color temperature controls, though the exact location varies by manufacturer.
  • On iPhone, Settings > Display & Brightness controls brightness and True Tone, while Settings > Accessibility > Display & Text Size holds color filters.
  • Color temperature (warm versus cool light) is separate from brightness and affects how yellow or blue your screen appears.

Changing color on Windows

Open Settings by pressing the Windows key and typing "Settings", then click the app that appears. Go to System, then Display.

You will see a brightness slider at the top. Below that is a section called "Color" with a dropdown menu showing your current color profile — usually "Standard" or "sRGB". If you want to switch to a different color profile, click the dropdown. Most people leave this on Standard unless they do photo or video work.

Below the color profile dropdown, you may see a toggle for "Night light". Turning this on makes your screen warmer (more yellow, less blue) in the evening, which some people find easier on their eyes. Click "Night light settings" to choose what time it turns on and off, and how warm you want it.

If you want more detailed color controls, scroll down and click "Advanced display settings". Here you can adjust contrast and sometimes access a "Color calibration" tool, though this is rarely needed unless your colors look noticeably wrong.

Changing color on Mac

Click the Apple menu in the top-left corner, then System Settings. Click Displays.

You will see a brightness slider. Below that is a dropdown for "Color profile" — this is where you choose how your Mac interprets color data. Most people use the default profile for their screen model. If you have a specific need (like matching colors for design work), you might choose a different profile, but the default is correct for everyday use.

If you want to reduce blue light in the evening, go back to System Settings, click Accessibility, then Display. Turn on "Reduce blue light" and set the schedule. You can also choose how strong the effect is.

For color blindness adjustments, stay in Accessibility > Display and look for "Color filters". Turn this on and choose the type that matches your color vision — Deuteranopia, Protanopia, or Tritanopia. You can adjust the intensity with a slider.

Changing color on Android phones

Open Settings and look for Display or Display and brightness — the exact name varies by phone manufacturer. Tap it.

You will see a brightness slider at the top. Below that, look for "Color temperature", "Color tone", or "Screen color" — again, the name depends on your phone's maker. Tap this option and drag the slider toward "Warm" to make the screen more yellow, or toward "Cool" to make it more blue.

Some Android phones also have a "Night light" or "Eye comfort" toggle that automatically warms the screen at sunset. If your phone has this, you can turn it on and set the time it activates.

For color blindness, go to Settings > Accessibility > Vision or Display. Look for "Color correction" or "Color filters" and turn it on. Choose the type that matches your color vision, then adjust the intensity.

Changing color on iPhone

Open Settings and tap Display & Brightness.

You will see a brightness slider. Below that is a toggle for "True Tone", which automatically adjusts your screen's color temperature based on the light around you. Most people leave this on, but you can turn it off if you prefer a consistent color no matter where you are.

If you want to reduce blue light at night, tap "Night Shift" in this same menu. Turn it on and set the time you want it to start and stop. You can also drag the slider to choose how warm the screen gets — all the way to the left is coolest, all the way to the right is warmest.

For color blindness adjustments, go to Settings > Accessibility > Display & Text Size. Scroll down and tap "Color Filters". Turn this on and choose Deuteranopia, Protanopia, or Tritanopia depending on your color vision. You can adjust the intensity with a slider below.

Understanding color temperature and why it matters

Color temperature is measured in Kelvin and describes whether light looks warm (yellow, like a sunset) or cool (blue, like the sky). A lower number like 3000K looks warm and yellow. A higher number like 6500K looks cool and blue.

Your screen's default color temperature is usually around 6500K, which matches daylight. In the evening, many people lower this to 3000K or 4000K because blue light can interfere with sleep — your brain interprets blue light as a signal that it is daytime. Warming your screen an hour or two before bed may help you sleep better, though research on this is still developing.

Color temperature is separate from brightness. You can have a bright, warm screen or a dim, cool screen. Adjusting one does not change the other.

When to use color profiles versus color temperature

A color profile is a set of rules that tells your device how to display specific colors. If you choose "sRGB" or "Adobe RGB", you are choosing a standard that defines what red, green, and blue should look like. Most people never need to change this.

Color profiles matter if you do photo editing, graphic design, or video work and need colors to match across devices. If you are just browsing the web or writing documents, the default profile is fine.

Color temperature, by contrast, is about the overall warmth or coolness of the entire screen. It affects every color equally and is purely a comfort choice. You can safely adjust this whenever you want without affecting how colors are supposed to look.

Frequently Asked Questions

Why does my screen look too yellow or too blue?

This is usually a color temperature issue. If it looks too yellow, your color temperature is set too warm — move the slider toward cool. If it looks too blue, move it toward warm. If the problem persists and looks like certain colors are just wrong (not the whole screen being tinted), your color profile might need adjustment or your screen might need calibration.

Will changing color settings damage my screen?

No. Adjusting brightness, color temperature, and color profiles are all software changes that tell your screen how to display information. They do not change the hardware itself and cannot cause damage.

Should I use Night Shift or Night Light all day?

You can, but most people use it only in the evening. Keeping it on all day makes colors look inaccurate if you are doing any work that depends on true color — like photo editing or choosing paint colors. For everyday browsing and email, it does not matter.

What is the difference between True Tone on iPhone and Night Shift?

True Tone adjusts your screen's color temperature based on the light around you — it changes automatically throughout the day. Night Shift is a manual setting you turn on at a specific time to reduce blue light before bed. You can use both at the same time.

Can I change colors to help with color blindness?

Yes. All major operating systems have color filters designed for different types of color blindness. Go to Accessibility settings and look for Color Filters or Color Correction. Choose the type that matches your color vision and adjust the intensity until colors are easier to distinguish.
