Do animations with a lot of red end up uglier looking but smaller in
size than, say, a "blue-dominated" animation?

  Isn't each color component handled separately?

No, I thought there was something about the compression algorithm that gives
red "extra compression" -- thus making it uglier but with fewer kb's.

The Official page of the MPEG is at:

http://drogo.cselt.stet.it/mpeg/

Enjoy... I'm sure you'll find sufficient information there.

NTSC is really bad on reds, and I believe that MPEG was meant to do video, thus
close to NTSC. PAL my also be bad.

Also, IIRC, the colors are broken down into Y Cr Cb. The Y is the brightness,
and the Cx components are the hue.
