lerp_color()

Calculates a color between two colors at a specific increment.

Examples

def setup():
    py5.stroke(255)
    py5.background(51)
    from_ = "#CC6600"
    to = "#006699"
    inter_a = py5.lerp_color(from_, to, .33)
    inter_b = py5.lerp_color(from_, to, .66)
    py5.fill(from_)
    py5.rect(10, 20, 20, 60)
    py5.fill(inter_a)
    py5.rect(30, 20, 20, 60)
    py5.fill(inter_b)
    py5.rect(50, 20, 20, 60)
    py5.fill(to)
    py5.rect(70, 20, 20, 60)

Description

Calculates a color between two colors at a specific increment. The amt parameter is the amount to interpolate between the two values where 0.0 is equal to the first point, 0.1 is very near the first point, 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.

Underlying Processing method: lerpColor

Signatures

lerp_color(
    c1: int,  # interpolate from this color
    c2: int,  # interpolate to this color
    amt: float,  # between 0.0 and 1.0
    /,
) -> int

lerp_color(
    c1: int,  # interpolate from this color
    c2: int,  # interpolate to this color
    amt: float,  # between 0.0 and 1.0
    mode: int,  # either RGB or HSB
    /,
) -> int
