I like red for laptops. I'm currently painting an OCZ DIY laptop I built for a friend of mine. Using burgundy and gold for an "Iron Man" look (which is what I named the laptop). Painted the outside top burgundy, going to do the rest tomorrow. I was going to use "Patriotic Blue", because he's in the Air Force now, but he said he prefers red. I'm getting a laptop for myself soon, too, and I might just go for a mirrored silver color for it - might have to name that one "War Machine"
I prefer darker colors in general. Would never use pink for any tech item.
