The enum declarator installs the elements under the Colors package as well as providing the short names, thus red can also be accessed as Colors::red. Therefore, one can use the package lookup syntax to do the job:

my Colors $color = Colors::{$foo};

Optionally providing an error or default:

my Colors $color = Colors::{$foo} // die "No such color $foo";
