Unless you have an express license or permission to make use of a derived work of Coors's trademarks, I'd just say that this is not so cool. Specifically, I doubt that you actually registered a "CorsLit" trademark, which completely mimicks the one by Coors Light, by keeping the ® symbol in place. Any trademark office would have rejected this registration.
I'm just an engineer, telling you this nicely. I'm sure, Coors will find other words, should your tool become more popular.
