Others tutorials: greyscale to color

There are so many resources of inspiriation and tutorials everywhere nowadays, can't hardly keep up with everything.

I'm too lazy to create an account on Pinterest, so I'm gonna start gather some of my favorite links and tutorials on this blog, just so I can have them all in one place. And why not sharing it with you guys as well? Many of you have probably seen them before, but I'll highlight them anyway ;)

I'm gonna start with linking to tutorials showing how to apply colors to a greyscale paintings.

I may have a few others in mind as well, which I can't remember at the moment. I'll add them later!
