I'm guessing one is natural light and the other is artificial lighting?

Not exactly...the upper row displays what the colours look like in reality and the lower row represents the colours how I wish they would look like (but I had to digitally add the blue hue...)

You know? I couldn't help but be reminded of the old 1970's TV Show "SWAT" where they had a similar problem when filming the big equipment van. The cameras saw it as "Black" but the viewers wanted to see it in a dark, LAPD type blue, so the prop makers ended up painting the van an off shade of pale, light blue, and Voila! In the films it looked the proper shade of blue. Are you shooting digital with incandescent or fluorescent lighting?
