The problem with your suggestion is that your partner might send a different but equally "guaranteed success" strategy (e.g. "...opposite color of the mixing result"). Then how do you agree on which strategy to use?

Or, take the critique mentioned in the article: Is red + blue called violet or purple? Same problem: You would need to agree on one name, and this conflict is not solved by you sending what you would call it - your partner might do exactly the same but with a different name.
