George Orr dreams away racism. Try it another way

Doctor Haber finally gets patient George Orr to dream an effective dream.
Dream away racism, Dr. Haber ordere. Racism has kept humanity in the dark, has kept humanity behind...Dr. Haber correctly intones.

I didn't like the results. Everyone is of the same or similar racial/ethnic background, except that we all have gray skin and gray-white hair. We look like moving statues or zombies.

HOW WOULD I HAVE DONE IT IF I WAS THE DIRECTOR?

I was watching an old horror film and noticed the lovely biracial actress, Jennifer Beals, and then I received the inspiration.
Instead of spray painting the actors gray-skinned, I would spray a light tan on to the actors so that everyone has a very light tan or olive complexion. On the hit reality show, "Dancing With the Stars", all the contestants undergo the spray-on treatment to gain an instant tan and they show it being done.
I would have all the actors' hair dyed to a narrow range of brown to dark brown to almost black straightened hair. Everyone would have dark brown eyes and convenient colored contact lenses would do the trick. Now for any black actors, we'd have to do a reverse spray treatment.
This way, everyone would appear to be from similar ethnic backgrounds while maintaining some semblence of individuality without looking like a Grecian statue or a zombie.
The other alternative is to hire actors and actresses who are already brunettes with some similarity which would make it easier to begin with but would still require some minor skin color spray and colored contact lenses for anyone with light-colored eyes.
TRIVIA:
Scientific theory now claims all humanity originated with brown to dark brown eyes. The blue-eyed mutation appeared only eight-thousand years ago in the Black Sea area of today's Russia. The blue-eyed mutation was in itself harmless, but made the human recipient very attractive to other humans and subsequently the mutation spread rapidly throughout western, eastern, and northern Europe.
