Source node
Ramp
A clean two-color gradient — linear, radial, angular, diamond, or spiral. Perfect as a soft backdrop, a mask, or a blend driver for another effect.
What it does
Ramp is a source node: it makes a picture from nothing, so it sits at the start of a visual chain. It has no input and gives picture out, so it starts a chain.
Try it
Multiply a radial Ramp over live video to vignette the edges of frame automatically.
