I'm really struggling to understand your question.  Are you concerned
about the case where "set -x" is in use, but a write to stderr *fails*
because stderr is closed or points to a file on a full disk or something?

If that happens, I don't think *colors* are going to be your main concern.

If you simply want set -x output and stderr from commands not to be
mixed together, use the BASH_XTRACEFD variable.
