Ah, that's my bad.  I shouldn't have used lightred, I should have used
red1 instead.

Yes, it is defined on pc-win.el.

I didn't add to `color-name-rgb-alist' more lightFOO colors beyond
what's already in rgb.txt, because it turns out that what's called
"lightred" on a VGA is actually called "red" by rgb.txt (judging by
the RGB values), and a similar situation exists with all the other
lightFOO colors (see pc-win.el).  Having "lightred" and "red" both map
to the same RGB values in `color-name-rgb-alist' would produce
confusing counter-intuitive results, which I wanted to avoid.

I will add a comment along these lines to tty-colors.el, lest someone
in the future will be tempted to add the ``missing'' colors.

What happens if you use "blue1" instead of "lightblue"?  Does it map
to 4, the blue color?  Does it look right in Info?  ("blue1" is what I
actually meant to use.)
