Colors bring us different feelings and emotions, while gradients bring us more imagination.

In computer graphics, a color gradient specifies a range of position-dependent colors, usually used to fill a region. The colors produced by a gradient vary continuously with position, producing smooth color transitions. Gradient color refers to the color of an object from light to dark, or from dark to light, or from one color to another, which is full of mysterious and romantic atmosphere.

Axial color gradients (sometimes called linear color gradients) are specified by two points, and colors are specified at each point. The color along the line passing through those points is calculated using linear interpolation and then extends perpendicular to the line.

Radial gradients are specified as circles with one color at the edge and another color at the center. The color is calculated by linear interpolation based on the distance from the center. This can be used to approximate the diffuse reflection of light from a point source through a sphere.
