Heads up: Dia Light / Dia Color is a demi color and Color System is permanent. Coverage, longevity and the final result will differ: adjust the service, not just the shade.
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 90 Dia Light / Dia Color shades, 20 exact, 51 close and 19 approximate in this chart with Color System. For example, Dia Light / Dia Color's 6 maps to Color System's 6. Natural reflects cross over best; other reflects ones need more adjustment.
Dia Light / Dia Color 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.
