By all means, fill me in on said tricks. I'm also curious to know if there are any specific limitations as to what colors can be next to each other, and if there are any limits on the range of colors you have available. If I had to wager a guess, it partly involves abusing luminance transitions, and partly involves the I and Q components having differing amounts of bandwidth available to them, and therefore, different effective horizontal resolutions for their particular portion of the signal.
