Brown Dun Mealy Roans??

Kairo

Marrok


So these boys are from the same sire (blue roan?) and dam (red dun roan?).. Kairo was always lighter than Marrok, and I was really excited to see what he would shed out as and it looks like a darker version of the full brother. I looked through the big dropbox file of colors and brown dun mealy roan seemed to be the closest match. Would this be correct for either one or both? Does Marrok's heavier roan just make him look a bit darker or is he actually darker on the spectrum of that one color?

To my (not very trained) eye, the first one is brown dun roan, the other brown roan without the dun, or at least a much more subtle expression of dun, probably. Marrok's head is dark without the dun mask Kairo has around the face mark, and Kairo's colour seems much more uniformly lighter under the roan specks.
And I don't see mealy on either of them, however subtle mealy would be hard to spot on brown. I don't see it on parents either (the sire would hide it even if he'd had it, as mealy is not visible on black; the dam doesn't seem to have it).
