Chroma

Chroma helps in simulating different types of color blindness occurring in humans.

The main purpose of this is to simulate 3 major Color Blindness types: Protanopia, Deuteranopia and Tritanopia for our different games and to aid the accessibility team in performing various complex testing.

Following are key features:

• Color simulation on a single monitor. This solution works on top of the game and can be maximized as per requirements.
• Works on all games. No dependency on any specific game or engine.
• High performance. Able to simulate live gameplay up to 60 FPS.
• Accurate results.
• Simulation of all types of color blindness.
• Only available solution which captures live gameplay screen and simulates colorblindness.
• Easy screenshots to log errors.
• Easy and configurable UI.
• For more details look into userguide here.

Here is an example comparing the default image with its Deuteranopia-filtered version:

Known Issue During CMake Process

If you encounter the following error while running CMake without Visual Studio 2022:

error C2039: 'wait_for': is not a member of 'winrt::impl'

This issue may occur due to an outdated CPPWinRT library. To resolve it, install the Microsoft.Windows.CppWinRT NuGet package using the following command:

nuget install Microsoft.Windows.CppWinRT

Alternatively, ensure that your development environment is using an updated version of CPPWinRT. The best option to avoid this issue is to use Visual Studio 2022.
