Rainbow Cake (or how to make Red Dye #40 look REALLY yummy)

So I am not usually one for insanely colored food unless it is in the form of fruits and vegetables, M&Ms or drinks that come with umbrellas. However, I stumbled across this cake on the HWTM blog and oh my...

There is something insanely appealing about this cake (and I mean insane). I think the psychedelic tie-dye colors sort of lull you into the sense that squirting a whole tube of gel food dye into cake batter is okay, heck it could be good for you. Then again, I drink Coke Zero like it is going out of style, so what do I know?

My only concern is that if I made a cake or cupcakes that looked like this, there may be kids (and adults) who are a little scared to eat it. I guess Funfetti cupcakes are a good, less pigmented backup. The full Rainbow Cake recipe is found on the Omnomicon site, but if and when I make this, we are going basic with just regular cake mix (minus the lo-cal additions that she posted). What do you think?
