Let's assume that people are actually tipping "people of color" worse. Do you think getting rid of tipping is somehow fixing this perceived racism? If so, why do you believe you can legislate a personality trait out of people?
No you don't. If tipped wages are more discriminatory you can ban them. Even if no racism is involved, somehow! And that's not trying to legislate a personality trait.
You're talking about taking jobs and money from a specific group of people so you can implement your ideological beliefs that have zero data to back them up.
You haven't provided any proof this sort of racial tipping exists but you've certainly provided plenty of proof of wanting implement your own racist ideas to redistribute money from a very specific skin color, while claiming other skin colors are helpless victims.
