I have never, ever thought about color or design when buying a bike. The only thing I've ever thought about is the fit and the components. I wouldn't look at a girly thing with flowers, but so far, no one has shown me a bike with that!
And I would never pay for special paint, decals, etc. I know this is important for some people, but to me it's just not important.
My bike is red, black, and a little white. When I needed new shoes, I got red ones, but I was wanting them anyway. I also eventually bought a red helmet, but I have a black and yellow one, too, which I wear regularly. I hardly had any red jerseys, though. Now I have 2, bought more because they were TE designs. My hybrid is blue, and I like that color, too. No matching helmet, but my shoes with spd cleats are blue, although I had them a long time before I bought the bike.
I care more about the color/style of my jerseys. The bike is all about the fit.
