Bob Ross® Yellow Ochre Oil Paint
Bob Ross® Yellow Ochre will be used moderately. It is used most often to mix various shades of highlights for trees and grass. Yellow Ochre is also used to make beautiful effects in the sky portion of your painting. If you paint often, the 5 oz tube will be the way to go, otherwise, the 1.25 oz tube should last you quite a while.
