vignette

Vignette effect. Darkens the edges of the screen or tints them with another color. It can be used to imitate some Arcaea anomaly effects.

Parameters

• color (color, default black [r, g, b, a]): Color of the screen edges.
• extend (float, default 0.25, range 0–1): How far the darkened edge extends. Larger values make the darkened area larger.
• radius (float, default 15.0): Size of the bright area in the center. Smaller values make the affected area larger.
