I wonder if this property sets a record for the greatest number of disparate, specific types a value is allowed to have in Cocoa. I'm talking about formal Objective-C types, disregarding semantics.

It can be an an NSColor, an NSImage, a CALayer, a CGColorRef, CGImageRef, or an NSArray of six images.
