Please, let's move away from red and green as "good"/"bad" colors. It's hard to tell the difference for colorblind folks, especially when the symbols used are quite similar.
Sorry about this. I assumed that checkmark/cross would compensate for this color combination, but I agree that better colors would make this more accessible for everyone. From what I'm reading online, Blue / Red is a better combination here?
That makes me wonder, if it should be solved client side by translating server side colours to something different on the client, according to the user’s needs.
There are absolutely solutions that do exactly that client side (just mapping the colors from the hard-to-tell-apart hues to other hues depending on which type of color blindness).
For instance, in Mac OS, under Accessibility there are 'Color Filters' with a dropdown for presets for a few common types of colorblindness including red/green. It is a filter that is applied systemwide at the graphic output level.
I think this is the proper approach (device-level color filtering) versus each app attempting to serve all, as that could lead to double-filtering.
