necrogenesis asked: What exactly do you mean when you say something like, "[Color] is primary/secondary/tertiary in [Ability]?" Are you referring to the frequency of the ability, power-level, or what precisely?
When a color is primary in an ability it means that they are the color that most often has that ability. The primary color will almost always have that ability in every set at common. Also, it’s the primary color that tends to grant that ability.
