godot-colorblindness

A colorblindness simulator to help you design for everyone.

The color calculations I use are heavily based on:

• Color Blindness Simulation Research
• Digital Video Colourmaps for Checking the Legibility of Displays by Dichromats
• This page on color space transformation matrixes
• The wikipedia page on sRGB

The Godot Ishihara plate has been generated with this tool.

Usage

• Install the plugin through Godot's AssetLib
• Activate it from the Plugin menu (AssetLib => Plugins button)
• This adds a new control called Colorblindness under Node.
• Create a new CanvasLayer and add a Colorblindness control to it in your scene.
• Specify the Type property (eg. Deuteranopia)

Everything that renders under the control will appear tinted to match your selected color-blindness mode.

Sample

The following sample shows normal vision, Protanopia, Deuteranopia, and Tritanopia (in that order).
