Re: Checker CSS and helper functions
Sure, take your time. I just wanted to give early feedback so that you can better understand our use cases and requirements.
No need to hurry with a design.
In the meantime I compared a bit more our different grids (i.e. DT, calendar, and others) and I think we need a few more colors:
- a color for grid headers (top and left edge of a grid), i.e. light gray
- a color for excluded or non-existing grid cells (like February 30/31 in a calendar grid), i.e. slightly darker gray
- colors for failed / partially passed (in progress) / passed / passed and selected
- a second color pair for failed / passed to visualize a different condition in another part of the same grid
"passed and selected" could for instance be used to highlight unique pairs of X and Y values or to visualize a streak in a calendar grid.
I [s]I also had a lengthy discussion with ChatGPT about color blindness. The most common color blindness is red-green-blindness. So a red-yellow-green color scheme for failed / in progress / passed is pretty common, but may pose a problem for color blind people.
ChatGPT claims that this color scheme works very well for all common kinds of color blindness.
Since I don't know any color-blind people in real life, I couldn't collect feedback how well these colors really work.

[s]For sure you need to get used to these colors if you expect red/green, but the scheme is not hard to understand:
- lightest color = failed
- slightly darker color = in progress
- medium dark color = passed
- even darker amber color = passed and selected
In this example color set 1 (yellow / orange / amber) is used for the cells in a DT grid, while color set 2 (blue) is used to visualize whether the sum of the cells in a line has reached a required minimum. The different color set is necessary to have a clear visual distinction between DT grid cells and cells with sums.
Feel free[/s]
Update: after doing a bit more research on this to suggest other pic, it seems that those color enhancements are done on client side (i.e. via operating system sets tings). It doesn't seem to be common that you a server delivers such optimized colors on demand.
I like more.the red/yellow/green color scheme better anyways.
