What is CGColor?

What is the difference between UIColor and CGColor?

A UIColor object is typically represented internally as a Core Graphics color (CGColor) in a Core Graphics color space (CGColorSpace). There are methods and properties that return the underlying color data. UIColor, is used to apply color operations on UIKit interface elements like UIImage, UIView etc…
