Color modeling and conversion framework in Swift
Overview
CoreColor is a color modeling and conversion framework written in Swift. It is designed for a wide range of audience, including color enthusiasts, engineers, visual designers and artists, as well as those involved in scientific researches that rely on color modeling.
CoreColor provides the modeling for a variety of common color models and associated color spaces, including common ones such as RGB, CMYK, HSL, HSV, LAB, and XYZ, as well as facilities for converting between a particular color model to any of the other ones.
Usage
The interfaces of CoreColor are simple and intuitive to use. Here’s an example of creating an instance of RGB color model in sRGB color space, and convert it to the equivalent CMYK model.
import CoreColor
let rgb = RGB(r: 0.40, g: 0.50, b: 0.60, alpha: 1.0, space: RGBColorSpaces.sRGB)
print(rgb) // RGB(r: 0.4, g: 0.5, b: 0.6, alpha: 1.0, space: CoreColor.RGBColorSpace(...))
let cmyk = rgb.toCMYK()
print(cmyk) // CMYK(c: 0.3333334, m: 0.1666667, y: 0.0, k: 0.39999998, alpha: 1.0)
