Automatic color management Creative professionals and enthusiasts care about fully calibrated, accurate colors because it helps to make sure colors remain consistent from the beginning to the end of their projects. Auto color management in Windows provides system-level color management to ensure that colors across Windows apps appear accurately and consistently on supported displays—whether the apps are color-managed or not. Auto color management also helps new and updated apps render more colors with greater accuracy. This provides extra detail and fewer color artifacts (for example, in gradients, shadows, and darker scenes or pictures). With auto color management, apps can use billions of colors with 10-16 bits of precision. Even on displays that only support 8-bit color, auto color management helps to improve color quality by using different techniques, such as dithering. To turn on auto color management Select the Start button, then select Settings > System > Display > Color profile . Select your display near the top, then check for the following setting: Automatically manage color for apps . Select Automatically manage color for apps to turn it on.
