Of the 17 Color Touch shades, 12 have an exact equivalent in Dia Light / Dia Richesse, 1 close and 4 approximate. The level (1-10) is universal; what varies is the reflect.

No. Equivalences are approximate because each brand uses different pigments, bases, and concentrations. The level (1-10) is universal, but the reflect result may vary. We always recommend doing a strand test when switching brands.

It's not recommended. Each brand formulates its products with specific chemistry (pH, alkalizing agent, pigment system). Mixing brands can create unpredictable reactions and unwanted results. Always use color and developer from the same brand.

The tool shows you the closest available shade. If you need a very specific result, you can combine two shades from the target brand (for example, mixing a natural with an ash to get a soft ash). Blendsor calculates these mixes automatically.
