How to convert CMYK to RGB in Node.js

Answer 1

// CMYK = Cyan, Magenta, Yellow, Key(black)
// RGB = Red, Green, Blue

function cmykToRgb(c, m, y, k) {
    const r = Math.round((255 * (1 - c / 100.0) * (1 - k / 100.0)));
    const g = Math.round((255 * (1 - (m / 100.0)) * (1 - k / 100.0)));
    const b = Math.round((255 * (1 - y / 100.0) * (1 - k / 100.0)));
    
    return [r, g, b];
}

const rgb = cmykToRgb(3.0, 17.0, 100.0, 0.0);

console.log(rgb);
