// Methods to treat an NSArray with three/four elements as an RGB/RGBA color.
//  Useful for storing colors in NSUserDefaults and other Property Lists.
//  Note that this isn't quite the same as storing an NSData of the color, as
//  some colors can't be correctly represented in RGB, but this makes for more
//  readable property lists than NSData.
// If we wanted to get fancy, we could use an NSDictionary instead and save
//	different color types in different ways.
