Froot Loops come in three different colors: Red, yellow, and orange, I think. Trix used to come in the same colors but now they have purple or blue or something, I'm not sure. I'm also not sure how many colors are in Fruity Pebbles but its probably the same. I do know that every so often they'll add a new color or "Berry-Blasted Swirls" or whatever. It doesn't matter because its all a rip-off. They might add colors or swirls or whatever, but they always taste the same. In fact, the individual colors don't even taste different from each other. They're not "cherry" or "lemon", they're red and yellow. They are vaguely "fruit-flavored" which in cereal language seems to translate as "anything sweet that's not chocolate".

I think a good cereal would be called "Cereal Killers". The front of the box might have a cartoon Unabomber. You could even have a promotional tie-in that said "goes great with O.J." or something. It could be like the police guy and the criminal on a box of Cookie Crisp, only this would be a Federal Agent and a Unabomber. And the little kid could always say to the Unabomber "Cereal Killers is just too good to bury in the crawl space under your house!" And the Federal Agent has a hard day ahead of him profiling sexual deviants, so he starts the day off with a balanced breakfast
