lchToRgb

The lchToRgb function converts LCH color values to RGB color values.

Syntax​

lchToRgb(l: number, c: number, h: number, asString?: true): string;
lchToRgb(l: number, c: number, h: number, asString?: false): { r: number; g: number; b: number };
lchToRgb(l: number, c: number, h: number, asString: boolean = true): string | { r: number; g: number; b: number };

Parameters​

  • l (number): The lightness value (0 to 100).
  • c (number): The chroma value.
  • h (number): The hue value (0 to 360).
  • asString (boolean, optional): Whether to return the result as a string (default is true).

Returns​

  • string: The RGB color string in the format "rgb(r, g, b)" if asString is true.
  • object: The RGB color as an object with properties r, g, and b if asString is false.

Throws​

  • Error: Throws an error if any of the color values are out of range.

Example​

import { lchToRgb } from 'colore-js';

// Example usage as string
const rgbString = lchToRgb(70, 25, 120);
console.log(rgbString); // Output: "rgb(161, 209, 143)"

// Example usage as object
const rgbObject = lchToRgb(70, 25, 120, false);
console.log(rgbObject); // Output: { r: 161, g: 209, b: 143 }

Usage​

The lchToRgb function is useful for converting LCH color values to RGB, which can be beneficial for various color manipulations and adjustments in applications.
