The Color Naming Rule is a set of guidelines that define how characters in the world of RWBY are named. The rules were first revealed by series creator Monty Oum as a guide for naming fan-created original characters. Virtually all canon characters follow the rule.
The rules state that names of characters in RWBY must live up to at least one of the following requirements:
- Be a color
- Sound like a color
- Mean a color
- Makes people think of a color
The name can live up to this rule through a combination of requirements. For example, it can sound like a word that means a color or makes people think of a color, and it can sound like a word that means something that makes people think of a color.
The rule applies to first name, last name and even the combination of the first and last name as well as their surname.
Characters usually have a distinguishing feature (clothing or hair/eye color) that matches their namesake, but this is not always the case.
In addition, all team names must be a four-letter acronym that spells a word that also abides by the above criteria.
During the Great War, one side destroyed art as part of their goal of suppressing all forms of self-expression. In defiance, those who opposed this tyranny began naming their children after a fundamental aspect of art - color. This symbolic gesture demonstrated that neither they nor the generations to come would tolerate such oppression. The latter group eventually prevailed, and the tradition of naming children after colors continues into the present day.
Barring some exceptions, all characters follow the color naming rule. However, exactly how the names of certain characters allude to colors is not always clear. This list attempts to extrapolate the intended connection in cases where it is not immediately apparent.
This list groups most characters of the show either by Team or association. All team names are four-letter acronyms that spell a word that is a color, sounds like a color, means a color or is evocative of a color.
