What is the difference between gouache paint and watercolor paint?

Gouache paint

Gouache paint is composed of powdery materials, fixed with glue, and has strong coverage. So when painting gouache, I often start with the darkest color. You can cover it layer by layer, and if you have good skills, you can achieve the same effect as an oil painting. However, the paint is darker when wet and becomes lighter as it dries. There are also purple-tinged colors such as rose red and violet, which are easy to turn out, so you don’t need to use them as a base.

Watercolor paint

Watercolor pigments have very fine particles. When dissolved in water, the color is beautiful, but it cannot cover the background color. Watercolor pigments such as ultramarine, ocher, and earthy red are mineral pigments. They are prone to precipitation when used alone or mixed with other colors. Most watercolor pigments are relatively transparent. Watercolor can enhance the transparency of objects, especially when used on the texture of transparent objects such as glass, metal, and reflective surfaces. Transparent and reflective surfaces are very suitable for expression with watercolor. When coloring with watercolor, proceed from shallow to deep, avoid overlapping strokes as much as possible, and it is best to paint in one go. The materials are different. Watercolor focuses on dry and wet painting. There is more water, very light colors should be used, and the coverage is small. Gouache painting is heavier. When it comes to painting, gouache has coverage, is relatively dry, and has a more layered feel.

Which is easier, gouache or watercolor

Gouache is easier to master than watercolor because it has strong covering power and can correct painting mistakes. The technique is relatively monotonous. , allowing beginners to focus on the study of form and color.

Whether it is watercolor or gouache, painters are required to master certain knowledge of color theory. Only by mastering the skills of color mixing and the corresponding color rules can a color be completed. work.
