(real living.) decorating dilemma

Usually I'm putting my thinking cap on for readers of real living, but today the problem is mine. I wrote about it here. I bought these great chairs the other weekend from Robert Plumb and have to decide what colour to get them powdercoated. Do I go for one colour - my preference, probably bright yellow - or four separate colours - white, yellow, orange and dove grey. What do you think?
