Interesting...I'm absolutely with Antstrat on this. The color may grab my eye, but if these three criteria aren't met, it's a no go.
There is one other factor for me. I like a guitar that has resonance to it, so there is a certain song that I play that has a G6/E chord in it. That may sound exotic to some, but it is simply an open E chord played at the 4th fret. If the guitar is resonant, that chord will bloom beautifully. If it doesn't gloom, it just sounds flat to my ears, and the guitar is a no go.
