Box shot?

A weird idea suddenly entered my mind

Maybe the three Episodes (I read that Penumbra will become a trilogy) will be coloured in the three "base" colours, Red, Blue And Green.

We have red now, and you have shown how good blue would work too.
Red was based on a flare, a red one, like the ones in the game, blue might then be an ice cave or something similar, and green... well, whatever green stuff might be, or maybe shouldn't be, but is, beneath the surface of Greenland
