Hi, I'm new here. I have a stallion that changes colors like a lizard! When we first got him as a baby, he was silver and white. ( He is a pinto with a lot of white). In the winter, his spots turn light yellowish brown but his face stays dark brownish gray. In the summer, he turns dark chocolate brown. I have no idea how to post pictures on here or I would post some of him. We just got our first foal from him this year, it was dark gray pinto with silver and white legs! Now she is turning dark brownish gray already. She is only 2 1/2 weeks old. I have got to send in the stallions perment record soon. I registered him earlier as gray and white pinto.I want to have him tested but I have no idea what to test for. Do I need to test for gray or black? I really wish they had a color for dummies book! All the colors are so confusing, they look brown but are actually black, or they look brown and are really silver. Help! Do I need to test for him being a tabino? I just don't know!
