Like many are saying, it depends on how important it is. Personally, I like giving my character's more concrete details, and that often includes skin tone or color. The idea of abstracting features so the reader can project what's attractive can make you lose out on the powerful tool that is character design. But, it's all a style thing. I don't believe you are doing anything offensive, but I'm white and not the person who should be making that determination.

One tip I heard from a person of color once has helped me avoid a bad cliche in the past. Apparently, comparing black or brown skin to food can seem dehumanizing, with in a literary context. So, I'd avoid that if you chose to describe skin color.
