Heads up: Topchic is a permanent color and Dia Light / Dia Color is demi. 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 109 Topchic shades, 43 exact, 46 close and 17 approximate in this chart with Dia Light / Dia Color. For example, Topchic's 6N maps to Dia Light / Dia Color's 6. Ash reflects cross over best; matte ones need more adjustment. 3 shades have no direct equivalent in Dia Light / Dia Color; those cases need a formula adjustment, not a code swap.
Topchic writes the reflect with a letter after the level (7N = medium natural blonde); Dia Light / Dia Color uses a dot (7.1 = ash blonde). The level (1-10) stays the same; what changes when converting is how the reflect is written.
