1) Determine the desired level for the final result.
2) Choose the fill color that is the undertone at the level that is 2 levels lighter than the desired end result.
If your final result is to be a Level 5, you would fill using the color that is the undertone of a Level 7. In this case that fill color would be Orange.
Desired Final Level: 7 =====>Fill Color: Yellow
Desired Final Level: 6 ====> Fill Color: Yellow/Orange
Desired Final Level: 5 ====> Fill Color: Orange
Desired Final Level: 4 ====> Fill Color: Red/Orange
Desired Final Level: 3 ====> Fill Color: Red
4) Fill always needs to be warm…the more damaged the hair the warmer the fill color needs to be
Remember that pourous/damaged hair no mater how reconditioned will always pull cooler than the shade applied.
