Brief introduction of gouache:
Gouache painting is a kind of painting made by mixing water and powdery pigments. Its performance characteristics are between opaque and translucent, and colors can produce gorgeous, soft, bright and rich artistic effects on the screen.
Powder content will limit the smooth activity of watercolor. Gouache has a high color saturation when it is wet, and loses its luster when it is dry, and its saturation is greatly reduced, which is the limit of its color purity.
Studying gouache can have a good understanding of color and a new understanding of color transparency. In the process of learning gouache, you can learn how to mix colors and further understand the importance of color to gouache.
Second, a brief introduction to watercolor painting:
Watercolor is a painting method that mixes transparent pigment with water, which is called watercolor for short. Because of the transparency of color, one layer of color can cover another layer to produce special effects.
But if too many colors are mixed or covered, the colors will be dirty and the water will dry quickly. Therefore, watercolor painting is not suitable for large-scale works, but suitable for small-scale paintings such as landscapes.
Watercolor pigments are easy to carry and can also be used as materials for sketching and collection. Compared with other paintings, watercolor painting pays great attention to expression. Its painting methods are usually divided into "dry painting" and "wet painting".
