MySQL / MySQL Overview / Process States Colours are Illegible (dark on dark background) #181

Open gordan-bobic opened 1 year ago

gordan-bobic commented 1 year ago

Colours of the lines on the Process States graph need to be changed. Apart from the idle line, most others are completely invisible on the dark background, especially updating, statistics and executing.

On a more general note, Is there something systematic we can easily apply to make sure that colours of graphs are such that the sum of R+G+B is always at least 384 (about half of maximum (255+255+255=785))?

Unfortunately, I couldn't find a way in Grafana to auto-generate such light colors in that RGB range, we have to assign a custom light color to each line manually.

That is unfortunate. Can you just bump up the colour brightness on the template for that graph? I don't think new states will be appearing often on that graph, so setting them statically is probably not the end of the world.

Actually - does newer Grafana do something more sensible? I think the background on newer versions is solid black, so that should bump up the contrast anyway. Let's park this for now and revisit later.

The newer Grafana changed their color scheme, but I still find some colors not very clear on that background

Since we build Grafana by ourself, we can add a patch to change that color scheme at build time.

I'm not sure I like the idea of maintaining our own fork of Grafana on top of everything else we have to maintain. Let's park this for now.
