This looks wrong or at least not the Guice/Weld concept like.

Afair Guice/Weld usage goes like this:
@Blue @Red class FooX implements Foo
@Blue class FooY implements Foo
@Inject @Blue Foo foo
it would throw an exception not knowing which one to choose, as both are supplying @Blue.
You would have to be more precise, having both @Red and @Blue on injection point.

The default qualifier on the bean/class shouldn't imply exact matching,
it should just imply that we always need that qualifier for all (non-explicit?) injection points.
