Color differences in two Operating Systems

Color differences in two Operating Systems



In our Testcomplete project we have a lot of region checks that were recorded on a Windows 8.1 machine. Testing on a Windows 10 machine leads to these checks failing due to Color Differences.


This can be seen in the following:



Left is Win 8.1, Right is Win 10.


I've checked the Bit Depth and both PCs are 32-bit color depth.


Adding a tolerance to every check in the project isn't an option as there are color differences required in some tests.


Is there any way we can solve this? Are these Windows specific settings?

Two ways to consider:

a) Use some intelligent image comparison tool/platform. E.g.: Applitools Eyes;

b) Keep a set of baseline images for every OS/desktop size/color depth/etc.

Found the fix. Had to edit the highlight rgb in the registry.
