Closet door with paint on them

Previous owner painted the bottom 2 ft of the MBR closet doors, and parts of the floor, etc. How and what do I do about them? I would like to paint them with a darker shade of what will be on the walls, as they probably won't take a stain with the bottoms done in white paint. Or should I try to match the stain color with paint?
