Ins't it still possible to construct the zero value for Color ? Like how bytes.Buffer does it https://pkg.go.dev/bytes#Buffer https://pkg.go.dev/bytes#Buffer : the implementation is not exported but you the usage is to construct the zero value and use it. So unless Color{} is a valid enum value, this solution would not work.
