The colour coding doesn't really have good-enough contrast. I can't personally distinguish the three first colours. I can tell they're somehow different, but can't tell which is which. All three are some kinda of "olive-like greenish". Maybe try going with better contrasting colours? Here's a useful tool to better test this: https://contrast-ratio.com/#darkolivegreen-on-olive https://contrast-ratio.com/#darkolivegreen-on-olive It's funny, I've always read a lot about these accessibility issues, but this is the first time I find myself affected by one to the point where I can't interpret something.
