“Hot pink” is an invention of the 20th century, in 1947 by fashion designer Elsa Schiaparelli, by adding a bit of white to magenta. I can’t think of a single other color that it doesn’t work well with. “Hot Pink” might be the new black (or white) because there’s no other color that goes with all other colors as successfully as pink.
