godot-colorblindness

A colorblindness simulator to help you design for everyone.

If you like godot-colorblindness, please consider buying me a coffee:

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 CanvasLayer.
• Create a new 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.

Known issues

• Setting Framebuffer Allocation to 2D without Sampling makes the addon unusable (#4).

Sample

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