You can't process me with a normal brain.

Asteroids didn't use a normal raster display, but a vector based one instead (the electron beam wasn't just deflected from left to right, and then top to bottom, it was used to draw the polygons on the screen). I wanted to know how they did the different colors.

Turns out the process for displaying different colors was the same as some of the original color TV experiments. And since I was already reading up on color TV, I wanted to make sure I remembered how the various masking techniques worked (I did), and picked up a little more insight along the way.
