Have you ever wondered about the numbers on hair dyes? Well, the numbers are part of a universal hair colour system. The first number is the base colour, which means 1.0 is dark black and 9.0 is a light blonde. The second and third numbers show reflect. The higher numbers mean warmer reflects e.g. 1.0 is dark black with no reflect and 9.8 is blonde with extremely warm reflects.
