Starlight is an ansi color theme focused on usability.
It was made after I made the discovery1 that I have a color perception deficiency: I have trouble differentiating between hues of blue (a greater one than the average person, making it impossible for me to read typical default blue text on black backgrounds). I also have a mild deficiency along the same lines for red, but not nearly as bad. I set out to make a high contrast theme that would work for me (a non-normative survey helped discover that some others have no issues with this content, while a few others do still struggle, but due to not struggling as much as I do, they simply live with it).
This repository is me sharing it.
You can find the exact rgb data in colors/colors.sh.
Other files inside of colors/*.sh are generators for various applications I use.
The goal is for me to only need to modify colors/colors.sh and the explanation/implementation section whenever I make adjustments.
You can find a list of things using starlight in the USERS file.
- All base colors (black, red, green, yellow, blue, magenta, cyan, white) should be easily uniquely identifiable.
- Bright variants should be identifiable side by side, but do not need to be uniquely identifiable.
- Text in any color (except black) should be legible on the black, even when not bold.
See the CHANGELOG to see implementation details.
A lot of the tooling present is usable as a template for other ansi color schemes.
To use it this way, modify colors.sh and set your own colors, re-using all of the other scripts as-is.
Don't forget to add a screenshot to data/ and modify the README!

I now have an actual diagnosis: tritanomaly. It's sufficiently rare that health professionals where I live do not screen for it when checking for colorblindness. ↩
