"...is a color..." Gad, I never knew about this usage. Good to know.

I didn't know that either. I experimented a little with this.
put "255,255" is a color --> false, but
put "255,255,255,34" is a color --> true,
hence the need for the extra check for the number of items = 3.
But beware:
put "255,255,401" is a color --> true
so the range is not checked, instead 401 is "wrapped" (mod 256) to 146
when the color is set to such a triplet
For a really strict parsing in just one line, I suspect you have to
use Regex. Notice I said "you," since *I* can't use Regex to save my
life, though I'm happy to copy and paste snippets provided by others
into my scripts when needed....
