A palette is a flat surface used to blend and hold fresh paint. It's usually a round palette or an oval palette. According to the shape can be divided into round palette, oval palette, rectangular palette, etc.

Palette is the springboard of painters' creation. It is difficult to determine the time when the palette came into being, but as a necessary tool for oil painting, it can represent the personality and work spirit of painters. Some painters use color palette before making coloring, so as to search for large color structure, and then put these colors onto the screen.
