Gouache Opaque watercolor paint. Most commonly used for commercial illustration. Can be mixed with transparent watercolors to make less opaque. These paints are made by adding chalk to the pigments to make them opaque. The use of gouache goes back to medieval manuscript illumination and was used in 16th - 18th century minature painting.
Many painters combine gouache, pastel watercolors and India ink in the same painting.

The actual practice of graffiti goes back to the Egyptians, but it was not thought of as an art form until the 1970's when the art world saw the work of street teens in the New York subways. There were some shows and artists acknowledged, but as soon as the raw street art came into the galleries of New York, the interest faded.
