The difference between gouache and watercolor

The difference between gouache and watercolor is as follows:

1, different transparency:

Watercolor pigments have high transparency. When colors overlap, the color below will penetrate. The color is not as bright as colored ink, but it is very dark, suitable for people who like quaint colors. It is not easy to change color even if it is stored for a long time.

Gouache is a kind of watercolor, that is, opaque watercolor pigment, which can be used for heavy coloring, and there will be no uneven phenomenon in large-scale coloring.

2. Their water-solubility effects are different:

The wet and dry shades of water-soluble colors of watercolor pigments and their penetrating effect on paper make watercolor painting have strong expressive force, form a wonderful changing relationship, produce transparent, hearty, dripping and fresh visual effects, be fantastic and natural, and grasp the beauty of harmony and agility with nature.

Gouache pigments are beautiful in water, but. The coverage is weak and cannot be modified. When painting, you should add more water and cover the color layer by layer, from shallow to deep, from wet to dry.

3. Wet coloring and dry coloring are different:

Gouache pigments can be covered layer by layer. If you are patient, you can draw the same effect as an oil painting, but the color of the pigment is darker when wet and lighter when dry.

Watercolor pigment is painted layer by layer on a dry background, which does not need infiltration effect. It can be easily painted repeatedly, easy to master and suitable for beginners to practice. Clear physical structure and rich color levels are the specialties of dry painting.

Extended data:

Byzantine painters have been making "watercolors" with resin for a long time. In addition, most decorative paintings in medieval manuscripts in Europe use watercolor, which is a new achievement of watercolor in another field.

Although there is a long history of mixing colors with water, ancient mixed water painting and modern watercolor painting are not the same thing. It is hard to say that modern watercolor painting developed from ancient ink painting. Due to the tools and techniques of modern watercolor painting, it has experienced many complicated changes in the course of historical development. Moreover, the characteristics of modern watercolor painting are difficult to find traces in ancient watercolor painting.

The characteristics of modern watercolor painting make it hard to believe that it is the result of the development of ancient watercolor painting. However, it is also wrong to make a clean break between ancient Shuidiao painting and contemporary watercolor painting, and it is not comprehensive to think that there is no connection between them.

Because any painting form is related, the development of any painting form is interspersed and has nothing to do with other art forms. The closed art form developed independently does not exist and is impossible.
