Replace color in UIImage with give tolerance value
// color - source color, which is must be replaced
// withColor - target color
// tolerance - value in range from 0 to 1
func replaceColor(color: UIColor, withColor: UIColor, image: UIImage, tolerance: CGFloat) -> UIImage {
// This function expects to get source color(color which is supposed to be replaced)
// and target color in RGBA color space, hence we expect to get 4 color components: r, g, b, a
assert(color.cgColor.numberOfComponents == 4 && withColor.cgColor.numberOfComponents == 4,
"Must be RGBA colorspace")
