Did you know that a significant percentage of your players have some form of impaired color perception? Common color combinations can cause great difficulty for these players. They can even make your game impossible to play.

Accessibility in gaming is a growing concern. Simply add this asset package to your existing game to immediately see how your game might look to a player with impaired color perception. No more tedious screenshots. No more clunky image conversion tools. No more guessing. Real-time color blindness simulation allows you to instantly spot problems without changing any part of your game or testing workflow.

Three types of color blindness are modeled and can be switched between at any time. The package includes a demonstration to show the real-time simulation in action, to help you learn about problematic color combinations, and to help you select colors which will work well for those with impaired color perception.

NOTE: This is designed for testing in a Windows environment with shader support (DirectX/HLSL). If you require testing on an OpenGL device, please contact me for additional support.

I'm glad to see other developers concerned about accessibility in GMS. I won't be using it in my game since it won't need it but a great diagnostic tool.

Thanks for making this, it was really helpful to see if I needed to adjust anything in my game for color blind players.

Easy to Use

Interesting and useful

This is a very interesting tool, and something that I'd never have thought of. It would be very helpful if there was a way to toggle a color scheme that would counteract the color blindness. That way you can have easy-access color blindness support.

Nice asset

If you want to see what your game looks like to a color blind person and perhaps adjust the color scheme to be more friendly to those people, you can do it with ease with this. It enables a shader for drawing the application_surface so all you need to do is create the supplied controller and set the mode to the disability you wish to visualize and the game will render in that disability so you can make sure your game has a good range that is distinguishable by people affected by the disability.
