Orange hair do care! I corrected it by using, 1:2 ratio of Ion Demi Permanent 10NA and 10 Volume Developer. I added 3 capfuls of Wella Cooling Violet and a small pinch of the Ion Ash Intensifier. ETA=I will use only the Ash intensifier and up the amount. I will omit the Wella cooling violet. Violet is used for unwanted yellow tones, Blue is for orange tones.
