hexColors (string[]): The list of hex color strings (e.g., ['#ff0000', '#00ff00']).

numColors (number): The number of distinct colors to retrieve.

threshold (number): The threshold for color similarity (lower values mean more similar).

- Returns:

(string[]): The list of distinct hex color strings.

- Example:

const colors = ['#ff0000', '#00ff00', '#0000ff', '#ff00ff'];
const numColorsToRetrieve = 2;
const threshold = 20;

const distinctColors = ColorUtils.getDistinctColors(colors, numColorsToRetrieve, threshold);

const rgb = { R: 255, G: 0, B: 0 };
const hex = ColorUtils.rgbToHex(rgb);
console.log(hex); // Output: '#ff0000'

hexToRgb

Converts a hex color to an RGB color object.

- Parameters:

hex (string): The hex color string (e.g., '#ff0000').

- Returns:

(RGBColor): The RGB color object. - Example:

const hex = '#ff0000';
const rgb = ColorUtils.hexToRgb(hex);
console.log(rgb); // Output: { R: 255, G: 0, B: 0 }

generateColorPalette
