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.

Of the 95 INOA shades, 29 exact, 46 close and 20 approximate in this chart with Color System. For example, INOA's 6 maps to Color System's 6. Natural reflects cross over best; other reflects ones need more adjustment.

INOA writes the reflect with a dot (7.1 = ash blonde); Color System uses a dot (7.44 = intense copper blonde; .2 = pearl/iridescent, .7 = violet). Both brands write the reflect in a similar way, so reading the code across is straightforward.

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.
