It's no wonder. You can do some wonderful things with it. I'm often asked for advice on mixing acrylic, and about the unique characteristics of acrylic when people make the transition from oils.
Nothing beats taking half a morning to just do a couple of exercises.
You can learn a lot in a short time. Select a limited number of pigments and test their strength and characteristics when mixed with white and black and opposites on the color wheel. Try the intermixture of some of the various modeling pastes and note their effects. See how they look when set beside one another. Simultaneously do some reading about the various color systems and find in your exercises how acrylics are practically the purest medium in which to test color theory.
