People with this type have a little coloring at birth. The most severe type of albinism is oculocutaneous albinism which causes white or pink hair, skin and iris color as well as vision problems. Another type is ocular albinism type one, affects just the eyes. The person's skin and eye colors are usually in the normal range.
