2D Generator - This generator creates a linear gradient (by default from black to white), in a circle from the center to the edges of the layer
It is possible to change its center, the colors used and their number, or to use keyframes for even more control over the color interpolation.
You also can play with the opacity of each color in the gradient.
Parameters
Ellipse (Ellipse) : Position and shape of the radial gradient
