Shade shaming: mocking, ridiculing, or teasing someone about the amount of melanin in their skin. #shadeshaming
Examples of shade shaming: You're not black enough. You're SO dark!". You need to cover up those freckles!"
or white people, you know you love this one--"you're so PALE! You need some sun!" And of course, there's the infamous "what ARE you"? The only reason to ask a person "what" they are in terms of race is because you're going to form a new opinion of them based upon their answer, which is...you guessed it...a form of #RACISM.
