Color System writes the reflect with a dot (7.44 = intense copper blonde; .2 = pearl/iridescent, .7 = violet); Koleston Perfect ME+ uses a slash (7/1 = medium ash blonde). The level (1-10) stays the same; what changes when converting is how the reflect is written.

Common questions when converting between these brands

Of the 56 Color System shades, 27 have an exact equivalent in Koleston Perfect ME+, 29 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.
