Very awesome eye for details! I can only imagine how neat that would look colored.
I'm afraid coloring it isn't going to happen...I haven't quite learned how to do that level of detail in colored pencils without things blurring up too much. But to give you an idea, the longcoat and trousers probably range in shade from tan to orange to brown, with a few details in black and red. The undershirt may well be a shade of green-blue, though with Daro's hair and complexion, he could probably pull off orange that close to his face.
