If you've read my other thread you'll know that we recently rescued 2 foals from a centre. One is brown and white (Summer) so we're sticking with Skewbald, but the other (Spring) is slightly more difficult.
Also, i'm not sure if age makes a difference with colouring? They are 8 months old.
Spring is black all over, with a white star. However, the ends of her mane are a light brown and she has a white tail? I don't have a picture to show her tail at the moment, but in this picture you can sort of see her mane colouring:
