For Koleston Perfect the ratio of developer is 1 to 1.These tubes are 2oz. each. So 2 oz. of developer per tube .... So for 1 ounce color you need 1 ounce developer.
EXCEPT for Level 11 & 12 Colors ... All Level 11 & 12 Colors in ANY Line of Color ratio is 2:1............2 ounces of developer to 1 ounce of Color.
Please remember Wella comes 1 full level darker than other lines. So if you are wanting a level 7 you should buy a level 8. This is the one and only hair color you should use if you are trying to cover gray hair above 25% Gray.
You take a NEUTRAL "N" in 1 level above what you want to be...... and mix it with your tone. If you are fighting Orange or Blorange you would always use a MATT color. Because Matt Tones are based in orange and that will work to counter the BLORANGE in your hair.
Lets say you are trying to achieve a level 7 and you have 30% gray and are fighting some you would take 8/2 + 8/0 + 20Volume on your base (roots)let that sit 20 minutes then apply just 8/2 + 10 Volume to the lengths if the Blorange is subtle OR..........
8/2 + 20Volume to the lengths if the tone is medium to strong Blorange (brass-gold-orange)
