Yeah, that overlay feature is neat, I've done that too with computer colored things, like add an orange layer to make the scene cozier, or a blue one for night scenes. As I've colored in the computer before trying traditional media I've found it somewhat unfortunate that physical colors don't quite work like that when you do glazes to change the mood. I guess because colors turn out when layering pigments depends on so many things, whereas digital colors are quite predictable.
