When it comes to color, no two brands or colors are exactly the same. This is because each brand's colors are comprised of an entirely different set of codes and sometimes varying color families.
To better understand these color codes, we’ll start with the basics.
COLOR FAMILIES
Becoming familiar with color family ranges is the first step in understanding color.
In general, the color families will work like this:
Black: 1-2
Brown: 4-12
Blonde: 14-26
Natural Red: 27-33
Vibrant Red: 130-134
Grey: 34-60 & 92
Platinum: 101-104, 613
A general rule of thumb with blacks and browns is that lower numbers will be darker, whereas higher numbers will be lighter. For example, if you are looking at the color R4 by Raquel Welch, you will see that it is a dark brown, whereas the R10 is a lighter chestnut brown.
