Sorry to fill the list with stupidity!
I forgot to do a retain on the NSColor I was creating. For some reason
not doing the retain didn't show up as a problem until I wanted to use
an alpha value...weird.
My example below was an oversimplification of what I was doing. I am
creating a NSColor in the constructor and using it later.
All is well now.
