The Soles Of My Feet Are Orange, And I Don't

The soles of my feet are orange, and I don't know why. The soles of my hands aren't orange, and I also don't have a large intake of carotene. My feet have been orange for about 2-3 years now. I am anemic, and in the summer I walk barefoot a lot. I play volleyball and that also may be hard on my feet. Please help me find out why my feet are orange, and a solution to this problem.
