Agree with all of the above.
Your questions should have been, "What do you think of this colt? Do you think he is worth running on, to see if he might be stallion material?"
I know nothing of his pedigree. What did you mean by colour? He certainly has some flashy markings. If you were thinking of producing tobiano or overo, then a lot would depend on the mare wouldn't it.
I'm tending to think by your question, that you probably don't have a good handle on equine colour patterns yet. Yes, he's a cute foal, but most are. Your best bet, is to learn all you can about colour (if that's your bag) and not breed again until you have it all quite firmly, in your mind. Anyone can breed. It takes homework and lots of learning, to know what one is doing, to produce a generation of horses, better than those who went before.
Before one breeds, a breeder should be able to look at a pedigree and know a great deal about many/most of the horses, up-front in that pedigree. Certainly, ask for opinions on quality, although your fellow is pretty young yet and might change quite rapidly as he grows.
