Description

Is your feature request related to a problem? Please describe.

There are currently two presets of color themes: default and no bright background. Unfortunately there are no presets for colorblind users, giving them a considerable and unfair disadvantage.

Solution you would like.

Two additional color themes since there is not just kind of being colorblind:

  • Protanopia & Deuteranopia for red/green color blindness
  • Tritanopia for blue/yellow color blindness
  • And optionally something addressing the complete lack of color vision (grayscale)

That would help these users to play the game.

Describe alternatives you have considered.

Using 24 bit color codes so you have a greater range of color. This would require a terminal which supports it but most already do. The greater range of color would make it considerably easier to find distinguishable colors.

Contributor guide

Research direction
Understand the current color theme system in Cataclysm DDA. Look at how 'default' and 'no bright background' presets are implemented. Then research colorblind friendly color palettes (e.g., for protanopia, deuteranopia, tritanopia) and modify the color definitions to create new presets. Test by enabling each preset and verifying visibility of game elements.
