I'm talking about the Civil Rights Act of 1964, which outlaws discrimination based on race, color, religion, sex, or national origin. You can discriminate against red-haired people but not black people.

It seems very unlikely that discriminating against red-haired people would survive a challenge since it is strongly correlated with specific races.

i.e. "we don't serve people with dark very curly hair", good luck with that one.
