NO, because this isn’t a copyright; it’s a TRADEMARK.
Trademarks have no set lifespan. Their lifespan is only limited by things like lack of use, lack of enforcement, and genericism (at one time “elevator” was a protected trademark; it is now a generic term for a particular device; “Velcro” could be next).
This color thing is a trademark, NOT a copyright, and as such, it has an indefinite lifespan.
Copyrights are different.
Their lifespan has changed over the years with periodic changes in the governing law.
Under current law (passed in 1998), copyrights on newly created and original works have a lifespan of the life of the author plus 70 years; there are somewhat different rules for works for hire.
Copyrights protect things like artistic works, sheet music, photographs, motion pictures, sound recordings, literary works, software programs, some architectural works, etc.
But they do not protect trademarks. That’s a whole separate class of Intellectual Property with a completely separate body of IP law.
Copyright Law is governed by the Cooyright Act of 1976 and a few revisions/provisions passed since.
Trademark Law, by contrast, is governed by the Lanham Trademark Act, as well as by some common law.
