Re: Why Gouache? Benefits? Why do you like it?
I work in a variety of media, and I find there's a certain cross-pollination that happens with the way I've learned to handle each one. The manner in which I apply gouache or casein can be used with oils or acrylics. It's essentially focusing on mixing the right color ahead of time. It's more of a general painting skill and not specific to the medium used; although, each medium has certain advantages or disadvantages by comparison.
I don't bother trying to make my acrylics look like an oil painting - why should I? Working in multiple mediums also keeps me on my toes and my skills sharp.
