practicality

Study stage and theater makeup. For speed it's definitely a matter of practice, but if you study show makeup you'll learn all the tricks about everything from proper coverage to crazy tricks like making realistic wounds. You'll also learn about how much color you need where based on what the lighting will be. People who look normal on stage look like clowns off stage, but that same intensity of makeup may be necessary for certain effects in normal lighting.

I never wear makeup, but being a backstage manager taught me everything about makeup I'd ever need to know. I'll try to find some resources for you, I don't have any of my books anymore but I'll find out what the titles were and see if I come across any good sites.
