What is a solid background?

There is only one color on the solid background, and there is no other pattern.

The light beam or spectrum is pure color, but there is no pigment or pigment that does not contain some components of other colors. In painting, a solid color may also refer to a color that is directly extruded from a tin tube and does not mix with other colors. Use only white to brighten the color, and use the same color to deepen the color, without other colors.

Extended data:

Some solid background will depend on the type of color, for example, the color of alizarin is pure and clear, while the color of Indian red is turbid.

In the visual image, the independent image corresponding to the visual foreground seen by people plays the role of setting off the foreground and coordinating the tone, and is generally used behind the plane or physical foreground, with far-reaching visual effects. For example, the picture after the page text is an independent picture, which is not connected with the foreground picture or image.
