enum Colors<red green blue>
say red; # OUTPUT: red
my $foo = "red";
my Colors $color = $foo.(...)
What code do I put in the Stub to convert the Str "red" to the Color red?

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";
