Of the 33 Illumina Color shades, 30 exact and 3 approximate in this chart with Color System. For example, Illumina Color's 6/ maps to Color System's 6. Natural reflects cross over best; red ones need more adjustment.

Illumina Color writes the reflect with a slash (7/81 = pearl blonde); Color System uses a dot (7.44 = intense copper blonde; .2 = pearl/iridescent, .7 = violet). The level (1-10) stays the same; what changes when converting is how the reflect is written.

Questions about Illumina Color and Color System

Common questions when converting between these brands

Of the 33 Illumina Color shades, 30 have an exact equivalent in Color System, 3 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.
