Generally, the blue color of the mono and multi-cristalline cells results from the anti-reflecting covering normally used, but the choice of possible colors is wide. In the market, there are, in fact, cells in grey, yellow, red, green, silver and pink.

Consequences on power
Despite the fact that the colored cells produce less power ("standard" blue corresponds to an optimization of solar irradiation collection), aesthetic factors could become more important than power factors, if the available surface is big enough to cover needs.
An example of performance of colored cells available in the market as compared to standard blue ones:
