I have two wtf. One has a white under belly, the other has an almost transparent under belly. The part under the mouth that unjulates is kinda clear and redish in color but not blood red. The other I have is white. I don't know very much about dumpy's but, I do see a big difference between the two. The 'transparent' one is more brown in color, the otheris more blue green in color. If you have any info, I would appreciate the insite.
