Gouache
- tool behavior directly shapes mark
- material preparation affects color / edge / durability
- maintenance and safety matter
What makes the subject recognizable
Material practice is an early parameter system: pressure, load, hardness, dilution and surface can be treated like variables in digital tools.
What the work is made with
These materials are not decoration added after the idea. Their weight, stiffness, opacity, manufacturing method or reproducibility help determine what forms are practical.
People and works to connect
Use these names as research anchors rather than a closed canon. The wider context includes workshops, manufacturers, patrons, collaborators and regional variants that a short reference page cannot exhaust.
How the visual system is built
Pressure changes the mark
Move the slider to alter width and opacity. Physical tools add more variables, hair stiffness, paint load and surface tooth, but pressure alone already changes the character of the stroke.
Historical contribution
Material practice is an early parameter system: pressure, load, hardness, dilution and surface can be treated like variables in digital tools.
Gouache: construction and behavior
Gouache is an opaque water-based paint usually related to watercolor through a gum-arabic binder but formulated with higher pigment concentration and, in many colors, greater opacity. It generally dries to a matte surface.
Because dry gouache can shift lighter or darker from its wet appearance, mixing requires experience. The matte, easily photographed surface made gouache popular for illustration and design work before digital production.
