I mean, I can hardly say that I "own" green on a light and dark base. That'd be absurd to say you own a particular colorway, perhaps one that was inspired by someone else's use of those colors, and then be upset when anyone gets even close to using it. Besides, I'm a firm believer that if you can design a colorway that accurately captures a source material in a manner that others that enjoy that source material can then relate it to that keyset, go ahead for something that people can enjoy as long as you're not straight up cloning. DCS really isn't my thing, but it's a neat looking set nonetheless.
