Sorry, this tutorial is incomplete. Ideally I'd discuss the process of coming up with color schemes for landscapes, but I'm only an amateur when it comes to that subject, so it's better people learn form the masters out there.
Unfortunately, no. Sorry. I learned more about color since this tutorial and probably could make a really nice one, but I don't have any plans for that at this point; I've been busy with other things.
Fret not, though. There are plenty of well-made tutorials out there for you on whatever you're looking for. If you have trouble finding some for your particular project, I can try to help you out with something specific. Good luck!
