Your questions on Gouache

Your questions on Gouache - Many of you have asked me questions about the gouache, I therefore collected the answers here for the benefit of everyone:

Carlos said: "After watching Gouache in the Wild, I'll finally buy gouache tubes I wondered if the same colors list that you published on the Watercolor in. wild station serves as a guide to build my first set. "

Carlos, these colors would serve you well. Basically, a high-chroma yellow (like a arylide Permanent Yellow ), bright red (like red flame ), then the earth color versions of yellow and red, such as yellow ocher and burnt sienna or Venetian red .

Then you would get a blues couple. Like cobalt, ultramarine, cerulean and Prussian, but I rarely take more than two of them at once in the field. I also like having a brilliant purple and Viridian. Again, it is mainly limited palettes, or if for some reason I have high chroma (saturation). And of course, you'll need white. And black, especially if you ever want to paint in grisaille pure black / white.

watercolor, gouache and crayons water soluble.
Mary said, "I watercolor sketch with minimal kit (small size Kit Maria card) and would be able to circumvent colored pencils if possible. do you think it is possible to sketch quickly and realistically without them? "

The answer is definitely yes. Painting with pure watercolor is quite good and you can get an effect you want with a single brush you. You can use the brush at a time wet and dry - brush dryer, flared out, give you all the effects of texture that you might otherwise get with a pencil the only problem with these extremely tiny kits is that you can not mix generous washes is transparent watercolor. . for an opaque sky or other large areas

Vodka Fashion said: "I just looked implementation gouache my paintings my question is, do you travel with real tubes, or. have you made a travel kit with gouache? I tried to do a travel kit, but paint dried. "
I travel with a small set of tubes in a plastic bag, ranging from two tubes (black and white) to about eight or 10 tubes. Sometimes I just carries a limited palette of three colors plus white. This forces me to do what I can with these colors. Although you can drag them into a type of watercolor palette, in advance, let them dry, then re-moisten them, they do not replenish the smooth they had when they came out of the tube. And there's the problem of rupture. If you just want to solve this problem of rupture, you can mix them with more glue as a binder soluble gum arabic , you can get in liquid or powder form.

Suzy Powell said: "So you just re-wet Where I live, we have 00000 Haha% of humidity (West Texas)
gouache no, I'm not re-wet dry gouache, except as a last resort, I used it? .. with low humidity and it dries quickly. it can be very frustrating on a hot day in the sun in a desert, in this case, the oil would be a best way. But for gouache, using a damp paper towel under the paint tightening of the tube will allow it to last longer. you can also extend the time by spraying your palette with a little water from a spray bottle. But once it is completely dry or worn it is best to reset the pallet off the cleaning and start with fresh squeezed paint .. do not keep dabbing where painting used to be

Matt Urbanowicz said: "I wanted to ask about the colors bleeding: I have a problem that although the gouache painting or display colors when adding layers I tend to pick up and fade the colors of the underlying layer, even when it is dry. Have I done something wrong?
Matt, yes, gouache will tend to look for if you put a wet layer on a previous layer, especially if you work with the brush at all. The fact that the surface can be reactivated can be a good thing if you want to soften the edges after the fact. But if you do not want these previous layers to come, there are two remedies. The first is to fix each shot quickly and without additional brushing. Make your motto "Make every race." Or "Think twice, press once."

If this does not work, you can use Acryla Gouache or Casein , who a closed surface when they dry.
