        While I will agree that red on black (and the reverse) is not good 
contrast in general, I have to disagree with this statement.  "Red" 
covers a lot of ground; from somewhere north of 'pink' to crimsons with 
so much blue in them it seems like they should be purple.  Some of 
those shades do have good contrast on black, some don't.  But the 
assertion that red doesn't have good contrast with black is a 
relatively recent one; until, oh, the 11th or 12th centuries it was 
pretty much accepted that it did, and even afterwards in some areas; 
you will find German coats of arms through 1600 that use red-on-black 
(and vis versa).  I would strong recommend against it (the English and 
French of the same period rarely used those two colors alone together, 
because they didn't consider them to have good contrast), but it can be 
done so it works.

        Blue is a bigger problem, unless you lighten it up so much it is 
essentially a tinted white.

        I know.  We could require everyone to use the national country 
coloring for race cars.  So almost all the cars at national events 
would have to be white with blue chassis and blue numbers...  But it 
would solve the contrast problem, at least until they got dirty.
