Animation of NSColor properties isn't supported yet; that's why your
code isn't being asked to provide an animation to use.
As an alternative, you could drive a float or double typed property
using an animation, and vary the color you use in response to changes
in that property.

The release notes on NSAmimatablePropertyContainer protocol give an

@implementation MyView

// By default, animate border color changes with simple
linear interpolation to the new color value.
return [CABasicAnimation animation];
} else {
// Defer to super's implementation for any keys we don't
specifically handle.
return [super defaultAnimationForKeyKey:key];
}
}

But I don't see the search for animations being performed on
properties that are not part of the primitives (double, float,
NSPoint, NSSize or NSRect). I have two properties on my NSView one
is float and does get animated, the other is an NSColor and the
defaultAnimationForKey: never gets called for this property.
Anyone else had a chance to mess with this api yet and seen the same
thing?
