color switch (カラーチェンジ) - Similar to a costume switch, except the character has retained their original costume, but switched their colors with someone else's.
costume switch - Two or more characters wearing each other's default clothes.
Never use this tag if there is only one character in the image who happens to wear another character's clothes or if one of the two characters in the image wears the other's clothes, but the other is still wearing his/her own clothes; use "cosplay" instead, if that tag is absent.
