Colors: Complete Guide

This guide provides a clear overview of colors, including the main concepts, practical steps, and common questions. Use it to understand the topic, compare the available options, and make a more informed decision.

Normally without ACM, Desktop Windows Manager (DWM) will restrict applications to output images only to 8 bits per channel, even on screens with higher color depth (optimized applications). can unambiguously target a wide color gamut by using the ICM/WCS color management API to match the colors of the display to the natural color depth). With the new ACM feature, DWM uses IEEE half-precision floating point to eliminate any possible 'clogging', and ensure all applications can access 10-16 bit precision. In a word, ACM can deliver color improvements even for displays with only 8-bit color depth using a variety of techniques, such as dithering.

The Auto Color Management feature is currently rolling out in the Dev Channel to Windows Insiders with build 25309 (appears as a hidden feature in previous builds). You can enable this feature by navigating to System > Display > Advanced display and enabling the Automatically manage color for apps option. However, it should be noted that turning on ACM can cause your GPU to consume more power, generate more heat and thus make the fan run noisier.

The new feature will work on most display models today, including standard 8-bit sRGB panels. However, for best results, Microsoft recommends using a monitor with a wider color gamut than sRGB or optional 10-bit depth. Additionally, your computer must meet the following specific GPU requirements:

To check the GPU model and WDDM driver, just press Win + R and type dxdiag .

Conclusion

Understanding Colors makes it easier to compare options, avoid common mistakes, and apply the information in this guide more effectively. Review the relevant requirements before making changes or choosing a solution.
