PYTHON APIfrom_hex
functionfrom_hex(hex: str) -> ColorCreate a Color from a hex string.
Supports multiple hex formats:
- "#RRGGBB" - 6-digit hex with full opacity
- "#RRGGBBAA" - 8-digit hex with alpha
- "#RGB" - 3-digit hex (each digit duplicated)
- "#RGBA" - 4-digit hex with alpha (each digit duplicated)
Args
- hex (
str) — Hex color string (with or without '#' prefix).
Returns
- Color — New Color object from the hex string.
Examples
from_hex("#FF00FF") # Magenta, full opacity from_hex("#FF00FF80") # Magenta, 50% opacity from_hex("#F0F") # Same as "#FF00FF" from_hex("RGB") # Without '#' prefix
from_hsv
functionfrom_hsv(h: float, s: float, v: float, a: float = 1.0) -> ColorCreate a Color from HSV(A) values.
Args
- h (
float) — Hue angle (0-360). - s (
float) — Saturation (0-1). - v (
float) — Value/brightness (0-1). - a (
float, optional) — Alpha (0-1). Defaults to 1.0.
grayscale
functionConvert a color to grayscale.
Args
- color (
Color) — The color to convert.
Returns
- Color — New Color object representing the grayscale version.
Example
grayscale(Color(255, 0, 0)) # Returns Color(76, 76, 76, 255)
invert
functionReturn the inverse of a color by flipping RGB channels.
The alpha channel is preserved unchanged.
Args
- color (
Color) — The color to invert.
Returns
- Color — New Color with inverted RGB values (255 - original value).
Example
invert(Color(255, 0, 128, 200)) # Returns Color(0, 255, 127, 200)
lerp
functionLinearly interpolate between two colors.
Performs component-wise linear interpolation between start and end colors. All RGBA channels are interpolated independently.
Args
- a (
Color) — Start color (when t=0.0). - b (
Color) — End color (when t=1.0). - t (
float) — Blend factor. Values outside [0,1] will extrapolate.
Returns
- Color — New interpolated color.
Examples
lerp(Color.RED, Color.BLUE, 0.5) # Purple (halfway between red and blue) lerp(Color.BLACK, Color.WHITE, 0.25) # Dark gray
