i'm not involving the correction skill of no one... just working on a poor image. I'm talking about the original or "start" image you uploaded. It's not a correction contest (or it is?)... BTW... my correction try to catch in the most natural way (i was not here i cannot say wich color the thing really is) the innate colors of the building. Realism... and sometimes this means low-color... anyway if your original has poor color informations you can't just add 'em... maybe wrong image for an example.
