Ramblings on watercolor and gouache
Both watercolor and gouache are water media. Theoretically, the difference between them is that with transparent wc you work light to dark laying thin glazes and washes on paper; gouache is opaque (dense), so you build up layers with brushstrokes, working dark to light. In actual paints, however, the distinctions are not so clear. Pigments used in all media are generally the same, so if you're using a certain color in watercolor, it's made from the same pigment used in gouache, oil or acrylics.
It's confusing to watercolor painters to learn that some pigments in transparent watercolor are highly opaque, for example, the cadmiums, cerulean blue and chromium oxide green. These pigments are naturally opaque, so they have more covering power than most watercolor paints. But they aren't as dense as gouache. Gouache has additives that make the paint more dense and opaque.
A gouache painting looks more like an oil or acrylic than a watercolor, although it's possible to make a watercolor that looks like gouache simply by using less water and more paint. The concern with either method is that thick paint may crack or break off the surface, which is one reason a more rigid support is needed, such as heavy illustration or watercolor board.
Transparent watercolor as a pure medium takes a lot of abuse these days from artists doing mixed watermedia and gouache. They claim watercolor's old-hat and everything has already been "done" in the medium. I don't agree with that. I love the splash and spatter of watercolor and the texture of the paper, the richness of a fine wash. There's nothing, absolutely nothing, as fine as a pure watercolor masterfully painted. I'm disappointed when I go to big watercolor shows and find most of the paintings appear to be acrylics or opaque watercolor. I can remember when the best artists in the country painted pure transparent watercolors and they were amazing.
I'm going to try some gouache, because I really haven't given it a fair trial yet. But I can't see myself giving up my watercolors.

I'm glad to hear you say that, Nita! I too am disappointed when I see so many acrylic paintings in the watercolor shows, as well as the "watercolor" magazines.

I have been reading about gouache, and saw a demo by Barbara Kellogg, who uses Holbein Acryla Gouache. It was fascinating; all the drips and pours and runs.
I bought some Absolute Matte at the CNY Watercolor Society's annual meeting. It's a new acrylic/gouache combo that made me curious. But I'm hesitant to try it because I'm so in love with transparency.
In fact, now I'm trying to slow myself down enough to experiment with multiple transparent glazes. Mostly I do fast, wet-in-wet stuff, with detail added later. So I'm learning to watch paint dry!

Wish I could have seen the demo. I admire Barbara Kellogg's work. I met her when I taught a workshop for the Cazenovia Watercolor Society several years ago. Gouache takes a whole different mindset, I think.
i am an artist see stuff at www.dallazlo.com and i am using gouache that has been diluted almost to watercolor,transparency wild violets and blues that really glow, i use them along with watercolor but do not do wet on wet w/ them together, am i going to regret this someday, i hope not, i really like the look.any hazards with this technique combo i should know about about?
As an artist who works primarily in gouache and very secondarily in watercolours, while not disagreeing with any of what you've said about transparent watercolour, I'm attracted to the celerity and immediacy of gouache. A tiny and perhaps not-that-relevant footnote -- in addition to diluting gouache with water, as expected (http://www.artbreak.com/work/show/2994-the-rapist-daniel-c-boyer) I've also diluted it with Coca-Cola instead of water (you can see an example at http://www.artbreak.com/work/show/2995).
I wonder what the point is in using Coca Cola to dilute gouache. I would be worried about insects attacking the painting.
