My friends welsh pony had a colt 2 days ago. He is a very strange mousy colour, a few people have said he might turn black which would be really cool but he could also be bay. His mum is bay (red carrier) and so is his sire who is a connemara, when I did the colour calculator he had 70% chance bay, 20% chestnut and 5% black. His colour looks dun or buckskin but there is genetically no way he can be those colours.
Here is a pic of him at 5 hours old
