Hi! Thanks for getting back to me, appreciate it. To be honest, I‘m not an expert at all in this topic. I‘d imagine choosing a colorblind-friendly palette (see: https://davidmathlogic.com/colorblind/ ) would be an easy fix. Alternatively, or in addition, you could use dotted/dashed/straight lines to visualize the latency buckets. Might make for an interesting effect?

Also it‘s common to hide this „colorblind mode“ behind a checkbox somewhere. So you don’t have to uglify your product. :-)
