Since angels are pure spiritual beings who can manifest in any physical form, depictions of them ought to be a diverse delight including all races, genders, ages, etc. Unfortunately they are almost always shown as white and the warrior angels like Michael almost universally as male. When I searched for female warrior angels I got a fan art blogpost that had some powerfully beautiful ones and also some sexually exploitative ones along with handsome but never over-sexualized male versions.
A nice exception in children's literature are the is Danuta Mayer's racially diverse angels in the beautiful (art and theology alike) book we loved when the kids were younger: Do the Angels Watch Close By?. Purchase. A search for black angels turned up a more conventionally Christian style site with some lovely images--but it is sad that this will mostly be searched for by, and marketed to, black people with general angel art following the haircare rule of regular human = white and ethnic/diverse/niche market = of color.
