Color Manipulation Package

This is a simple JavaScript package that provides functions for color manipulation, including converting between RGB and HEX color formats, as well as calculating the contrast ratio between two colors.

Installation

To install this package, you can use npm:

npm install colormanipulationix

Usage

const colorManipulation = require('color-manipulation');

// Convert RGB to HEX
const hexColor = colorManipulation.rgbToHex(255, 0, 0);
console.log(hexColor); // Output: #ff0000

// Convert HEX to RGB
const rgbColor = colorManipulation.hexToRgb('#00ff00');
console.log(rgbColor); // Output: { r: 0, g: 255, b: 0 }

// Calculate contrast ratio between two colors
const contrast = colorManipulation.contrastRatio('#000000', '#ffffff');
console.log(contrast); // Output: 21

• b: Blue color value (0-255)

Returns the HEX color value.

hexToRgb(hex)

Converts HEX color value to RGB format.

• hex: HEX color value (e.g., '#rrggbb')

Returns an object containing RGB color values { r, g, b }.

contrastRatio(color1, color2)

Calculates the contrast ratio between two colors.
