The types, characteristics, and placement techniques of pigments have always been a concern for students. Today, I summarized some knowledge points on these issues.
Characteristics of water powder
1. Water powder pigments are relatively viscous, with strong coverage, low transparency, fast drying speed, and obvious changes in dryness and wetness. They can be directly mixed or mixed with water, water powder mediators, etc. So in general, there are more direct drawing methods used, and it is not easy to integrate strokes with each other. Therefore, the expressive power of strokes is also one of the characteristics of gouache painting.
2. The personality differences of gouache pigments. Most of the colors of gouache pigments are relatively stable, such as earth yellow, earth red, ochre, orange yellow, medium yellow, light yellow, olive green, pink green, ultramarine, cobalt blue, lake blue, and so on. However, the colors of deep red, rose red, green lotus, violet, etc. in gouache pigments are extremely unstable, prone to color reversal and difficult to cover. There are relatively few types of transparent colors in gouache, with only a few colors such as lemon yellow, rose red, and green lotus.
Characteristics of different colors
1. Introduction to some commonly used colors: light yellow (warm yellow), medium yellow (warm yellow), vermilion (warm red), eosin (cold red), deep red (used to suppress dark red heavy colors), rose red (strong explosive power, anti color after drying, excellent effect when used less), violet (beautiful cold color), ultramarine (warm blue), cobalt blue (quite positive blue), lake blue (cold and bright blue) Blue (the heaviest color except black, used to accentuate the image), light green (warm green), medium green (more commonly used green, more positive), deep green (or olive green, used to suppress dark green), pink green (cold, good for apple painting), and grass green (commonly used for landscape painting).
