I have noticed lighting has a dramatic affect on color too. I bought in BLC Stans Golden Car in after half the flowers opened, but were bightly colored yellow, but the ones that opened in the house had much less color then the ones allowed to open outside. I have noticed that same effect on a brassia hybred too.
So if its not the color change issue that Phantasm bought up I would vote for lighting.
