For me, I would rank these qualities in this order: fit, performance, value, color. Its not that I don't think color is important, it is that I am very hard to fit, so if I find a bike that fits me with nice components and a good price, I find that is what makes me fall in love with the bike, and then the paint job grows on me. As Emily said, you can do a lot with accesories, the color of your bar tape, saddle, bags, tires, etc. Even if you don't need to change these things immediatly, you can have a replacement plan. But 'hate' is a strong word, and if you truly hate the color to the point that you think you wouldn't want to ride her, then absolutely don't buy her.
