Everywhere I looked today there was red green and blue. I had a hair cut just up the street from this building and I swear even the barber was wearing a shirt comprised entirely of RGB!!
BTW, I have NOT painted the sky. its all the same pic although I had to do two RAW conversions and do a quick magic wand to mask the blown sky and replace it with the corrected version - hence the roughness (you can tell I'm the REAL Slack boy around here!)
