Within one hour of touching the brush to canvas for the first time, my students have a total, complete painting. - Bob Ross

Absolutely have to have dark in order to have light. [...] Gotta have opposites – dark and light, light and dark – continually in a painting. If you have light on light, you have nothing. If you have dark on dark, you basically have nothing. [...] You know, it's like in life: you've gotta have a little sadness once in a while, so you know when the good times come. I'm waiting on the good times now.
