War of the Worlds was produced as a color game, but was test marketed with a B&W
monitor in a converted Star Castle cabinet. Unfortunately (or actually
fortunately -- if you've ever played the game) it never made it past test
marketing.

The ROMs supported the full color of the Boxing Bug color card, and when used to
drive a B&W monitor you end up with no intensity controls, all the vectors on
the B&W version of War of the Worlds are high intensity only.

Unfortunately (most) Cinematronics B&W games only used two intensities so Clay's
intensity to color mapping won't do you much good here. Even in the games that
support multi-intensities they make heavy use of fading so you would end up with
a rainbow of flickering colors instead of a nice fades in Solar Quest and
Sundance (the only multi-intensity B&W games).

The best bet for getting color in Cinematronics games is to hack the ROMs, now
if I only had a job like Clay's were I had time to do these sort of things...

....So, Clay, You're company wouldn't be looking for any embedded system software
engineers would they? ;^)
