Again, I'm not suggesting that color doesn't have value. I'm suggesting that
we shouldn't encode *information* in color that isn't otherwise present in
the text. That's very different from the color making the information more
valuable (often through improved clarity).

The problem is *how* you provide the degraded experience. Sure, in some
cases, the clang driver detects whether or not we have a terminal available
that can render colors. However, there are many cases where *after* that
detection occurs, the colors are then stripped out by various pieces of
software. This can happen with screen, ssh, log processing, some defective
terminals, etc. That means that we don't have the opportunity to generate
more text at the moment the color gets stripped. The worst case scenario for
me are problems of colorblindness. ;]
As for how to do it
Snipping the how. I'm interested in figuring out the "what" before focusing
on the how. I think Richard was actually looking at doing highlighting
already, so I suspect he has some plans.

Again, there is an important difference between "less value" and "less
