I, myself, am a bit colorblind, but not so much that I cannot discern the colors. On the other hand, as designed right now when damage is close to finishing your opponent off it is very difficult to see. I support an option to change the colors/split the bars/numerically show difference/whatever.
Also, a bit of advice, the hard stops like you're talking in a chat are somewhat difficult. If you could, paragraph form would make your posts easier to read.
