Steve is working on adding this functionality. Please > see the latest linux-kselftest next for the patch. I hadn't seen today's discussion until after Steve replied to this patch. Mine is based on your next branch, building upon Steve's patch. These changes here are somewhat different, in that color is enabled only if color is available in the terminal in the first place! And if the standard output is redirected to a file (which is what Masami reported today), then colors are avoided even if available. Greetings!

We still need to strip out the escape sequences from log file even if the terminal accepts colors. Anyway, this fixes the "black character" issue for me :) Thanks Daniel! Acked-by: Masami Hiramatsu <mhiramat@kernel.org> I'll add a filter patch on top of this.

If test is being directly executed (with stdout opened on the terminal) and the terminal capabilities indicate enough colors, then use the existing scheme of green, red, and blue to show when tests pass, fail or end in a different way. When running the tests redirecting the stdout, for instance, to a file, then colors are not shown, thus producing a more readable output.
