Gouache watercolors, definition and tools, how to use gouache colors

a definition  :

       Gouache colors, gouache, or holographic colors are all names for one of the types of watercolors, meaning their medium is water, despite the similarity of the substance that aids in mixing. Gouache colors differ in everything from watercolors, and what sets them apart is the difference in transparency, that is, watercolors are transparent, so they cannot mask the surface unlike gouache colors, which have the property of opacity, and they are not shiny, so they do not reflect light, that is, they are dull or matte.

Gouache colors and how to manage them:

     Gouache colors come in small bottles or tubes, and we use them in the same way as acrylic colors, which means that thanks to the coloring material it is possible to easily go from one color to the other, unlike watercolor, which requires a pattern from dark to light, making them easy to handle and suitable for professionals, beginners and children.

     Gouache is similar to watercolor in the way it controls color saturation and gradation, as they both use water to create gradations, so the more water we add, the less the color becomes opaque. color gradients differ from each other because they use the same property and are combined with the same medium.

     Due to their opacity and the materials used in their manufacture, gouache colors have a wide variety of surfaces which facilitate their use and their different modes of expression. They are compatible with all watercolor papers and most drawing papers in general, even the lightest, and for more effects. They are suitable for dark, i.e. black, colored papers and for different surfaces, such as wood, glass, etc., of course with surface preparation.

     We use soft or waterproof brushes to apply the drawing or makeup brushes for more differences in color strokes, and they are easily cleaned with water.

Gouache colors require special handling, as they must be treated in the same way as watercolors. Before starting to color, it is necessary to determine the required area and use the quantity appropriately depending on the area of the surface to be colored. , with brushes with a strong wetting force that allows you to cover the largest area of the surface in a single stroke.

    The advantages of gouache are its lack of shine and its ease of modification or modification, while acrylic, which is the closest material to gouache, has a shine and cannot be modified.
