one possibility for the colours on the wall:

the colors from the eyes, on each aerials-crew poster can be:

cyan black cyan magenta cyan black

the difference with what have been said before about these colors, is the black. I don't think it's a yellow, or an orange, but rather a dirty maroon-black.
If I'm right about this black, the colors and their positions are the same on the nokia youtube page (in the background image, when you select one of the 6 videos). And are the same as the real N9 apparition in each videos.

Can be related to the message to code or decode...

that's my 2 cents , this game is really fun.
