Static p5_sys::global::lerpColor

pub static lerpColor: LerpColorInternalType

Blends two colors to find a third color somewhere between them. The amt parameter is the amount to interpolate between the two values where 0.0 equal to the first color, 0.1 is very near the first color, 0.5 is halfway in between, etc. An amount below 0 will be treated as 0. Likewise, amounts above 1 will be capped at 1. This is different from the behavior of lerp(), but necessary because otherwise numbers outside the range will produce strange and unexpected colors.

The way that colors are interpolated depends on the current color mode.

Examples

colorMode(RGB);
stroke(255);
background(51);
let from = color(218, 165, 32);
let to = color(72, 61, 139);
colorMode(RGB); // Try changing to HSB.
let interA = lerpColor(from, to, 0.33);
let interB = lerpColor(from, to, 0.66);
fill(from);
rect(10, 20, 20, 60);
fill(interA);
rect(30, 20, 20, 60);
fill(interB);
rect(50, 20, 20, 60);
fill(to);
rect(70, 20, 20, 60);

Parameters

c1 interpolate from this color

c2 interpolate to this color

amt number between 0 and 1
