If I were to read all of the human races based on cartomancy/tarot cards, I'd say that the hair, eye, and skin colors of the court cards actually reflect on racial issues perfectly.
Hearts and Diamonds are definetly Caucasians (especially ones from Northern Europe). Hearts being blonde haired and blue eyed with fair skin, Diamonds being light brown hair, red hair, or dirty blonde with blue eyes, green eye, or light brown eyes. A combination of wealth and a better lifestyle iow 'white privilage'.
Clubs can describe your Caucasians with dark hair and dark or light eyes and light skin. Like people from the countries in the Mediterranean. I think they can also describe Asians and Jewish people with light skin and dark hair. Clubs are associated with hard work, wisdom, and creativity.
Spades can describe people around the world with dark skin, dark eyes, and dark hair. People like Africans, Arabics, Native Americans, dark-skinned Hispanics, Polynesians, Aborigines, etc. Spades represent "overcoming obstacles" in life, and often involve misfortune. Considering what the European colonists have done to so many of the countries in Africa, North and South America, Australia, the islands, and the Middle East, I'd say it's a fitting description. These people have been screwed over a lot.
Of course I don't believe in judging a person's character based on coloring. That's stereotyping. But for ethnic cultures around the world it makes sense in a way.
