Having the text change color is a little too much, and depending on the color the text might be harder to read or pop less out than regular white on black text. I think a color change on the users name instead would make a better choice. You will still stand out from chat but a little more subtle and easy to work with.I haven't seen all chat colors yet tho. Some may be better than others. And i do wonder how the black works on black? And how the colors work between light and dark mode. ^^'
