When the “similar” setting is even a little bigger than the minority setting, it is hard to achieve satisfiaction. For example, if the minority color is at 10% but satisfaction requires 15%, then you can’t find satisfaction. This tool shows that the absolute fastest way to be satisfied is to not care about the color of your neighbor. IE, the way to societal happiness is to be color blind.

Maybe not color-blind, but universally color-tolerant.

And then the relevant question becomes "How does one change human behavior and expectations?" That's an extremely non-trivial problem.
