Heads up: Koleston Perfect ME+ 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 152 Koleston Perfect ME+ shades, 54 exact, 51 close and 37 approximate in this chart with Dia Light / Dia Color. For example, Koleston Perfect ME+'s 6/0 maps to Dia Light / Dia Color's 6. Golden reflects cross over best; red ones need more adjustment. 10 shades have no direct equivalent in Dia Light / Dia Color; those cases need a formula adjustment, not a code swap.
Koleston Perfect ME+ writes the reflect with a slash (7/1 = medium ash 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.
