Also note NSColor's setIgnoresAlpha:, especially the last sentence.
"If the application doesn't support alpha, no opacity slider is
displayed in the color panel, and colors dragged in or pasted have their
alpha values set to 1.0. Applications that need to import alpha can
invoke this method with flag set to NO and explicitly make colors opaque
in cases where it matters to them. Note that calling this with a value
of YES overrides any value set with the NSColorPanel method setShowsAlpha:."
