I would say definite pali on the filly. Some of them are born darker than others and you can never really tell what shade they'll be until they shed out a couple of times.
As for the colt, there's no way to tell for certain. Sometimes pali's are so pale they look cremello and other times they are so dark that they look brown or black. I would say that he won't decide on his standard color until he's a couple of years old. Even then, sometimes they continue to change shade throughout their lives, depending on season and nutrition.
