The stallion is ee and could be any form of agouti. Just because he threw those colors on a different mare doesnt mean he can throw them with yours. You said your mare had a red parent correct? That means you will get 50/50 chances of getting a red or black based foal. Your mares Agouti status is aa and the stallion being sorrel doesnt show whether he carries agouti or not but seeing as how he has thrown a black filly he is either Aa or aa meaning 50/50 whether he could throw a bay or a black with your mare. So your only color choices are Black, bay, sorrel with a possibility of an overo gene from your mare. Just because he's thrown all those things doesnt mean they have come from him. The mares also provide genetics on the baby.
There is no way possible for him to throw a roan, or dun from your mare. And I did want to point out that you posted "He produces colts and fillies of colours ranging from palomino, chestnut, black, all the way to duns and roans. The only colour he has not produced is a grey and cream colours." However palomino IS a cream color.
