Heads up: Dia Light / Dia Color is a demi color and Koleston Perfect ME+ 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, 33 exact, 29 close and 28 approximate in this chart with Koleston Perfect ME+. For example, Dia Light / Dia Color's 6 maps to Koleston Perfect ME+'s 6/0. Natural reflects cross over best; other reflects ones need more adjustment.
