Who owns Coward Yellow?

" 'Post-It' and the color canary yellow are trademarks of 3M."

Ok, as a big "L" libertarian I'm all for the concept of intellectual property but it's time to confess my discomfort with the ownership of colors, naturally occuring gene sequences, and immortal Disney characters.

"While the banks get fat

And the poor stay poor

And the rich get rich

And the cops get paid

To look away

As the one percent rules America"
