Not trying to offend anyone here but saying something looks black isn’t racist. Making the remark also is not racist because he meant it descriptively. A burnt marshmallow is the color black, he didn’t make a remark that insinuated black people were less than or ‘burnt’ people he just made a descriptive remark. There’s a difference between making a remark that is meant to place ones race above another and a remark that is descriptive please learn the difference if you are in a mixed relationship because this sort of thing will happen again. It should only really be a problem if it is meant maliciously or mockingly and with the intent to punch down on your race.
