About the color, i'd say red dun, if he does shed out to another shade of color my next guess would be dunalino.
About the weight, it might not be how much your feeding, but WHAT your feeding him. Certain feed's will actually put weight on your horse, nutrition AND exercise is a very high factor in obesity. Just like in people, good exercise and diet need to be established before you will lose weight. Same goes with a horse, you could try a supplement to help him digest his food better, and help speed up his metabolism. Cutting his feed wont make him lose weight, less food AND exercise will help him lose weight. But can you honestly expect a morbidly obese horse to want to exercise? He'll lack motivation, and therefore it will be useless. I would try him on a sweet feed (in most cases it will give pep to a horse), or look for supplements to help give him a little energy. A horse with energy, is a horse that wants to burn it off with running and playing. If he has none because of his weight, even if you do try and get him to lunge, I doubt he will be a willing participate, and your friend will most likely give up "because he's being to lazy". If at all possible, could you work with him yourself? I know it doesn't sound "fair", but for the health of the horse, if you can't get your friend to, try exercising him your self.
EDIT: Also wanted to add, don't go out and try to work him hours at a time. To much stress can put the horse at great risk, do 15-20 minute work outs, several times. This will help his body adjust to the work out slowly, until you get to the point where you can increase the exercise. Simple trotting, turning, stopping etc will help, get him moving and working his muscles.
