Modifying Shades Separation Admixture during Coloring Wella Professionals Color id

Use only with Koleston Perfect or ILLUMINA COLOR and Welloxon Perfect/Color Touch emulsions (1.9% and 4%) in the following ratios: dye + Welloxon Perfect + modifier. For Koleston Perfect or ILLUMINA COLOR, use a ratio of 10:10:1; for Koleston Perfect Special Blonde, use a ratio of 10:20:2; for Color Touch emulsion 1.9%, use a ratio of 10:20:2; and for 4%, use a ratio of 10:10:1. Apply the dye mixture to dry hair using a spatula and arrange the strands in any direction you prefer.
Color.id can also be used to achieve a harmonious transition from one color to another. To do this, apply one color only at the roots, then use another color along the length of the hair to the ends, ensuring there are no uncolored sections between the two colors. Apply different shades to adjacent hair strands, starting with one shade on one strand and then applying another shade to the strand next to it. Arrange the strands however you like.
The processing time for Koleston Perfect and ILLUMINA COLOR (with or without heat) is the same as the techniques that do not use Color.id.
