How to read the match: Exact = same level and same reflect · Close = same level, same reflect family · Approximate = same level in natural, or adjacent level with the same reflect. Hover each badge for that row's reason.

Common questions when converting between these brands

Of the 56 Color System shades, 30 have an exact equivalent in INOA, 13 close and 13 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.

Yes. Inside Blendsor you'll find it in Learn → Brand converter and in the chat attach button (+). There the equivalent comes with its confidence level and a warning if the product type changes, and you can send it to the advisor to fine-tune it for your client's base, grays and porosity. Download the app.

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.
