There is a Unicode character PERSON WITH BLOND HAIR, but no corresponding PERSON WITH BLACK HAIR. This is obviously discriminatory. We need new emoji modifiers for: blonde-hair, black-hair, brown-hair, red-hair etc.
"As to hair color, dark hair tends to be more neutral, because people of every skin tone can have black (or very dark brown) hair—however, there is no requirement for any particular hair color. One exception is PERSON WITH BLOND HAIR, which needs to have blond hair regardless of skin tone."
