No direct equivalent in Topchic (1)

These Color System shades have no comparable level-and-reflect shade in Topchic. Switching ranges here means adjusting the formula, not swapping one code for another.

  • 1V Violet Black

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 58 Color System shades, 37 exact, 5 close and 15 approximate in this chart with Topchic. For example, Color System's 6 maps to Topchic's 6N. Ash reflects cross over best; matte ones need more adjustment. 1 shade has no direct equivalent in Topchic; those cases need a formula adjustment, not a code swap.

Color System writes the reflect with a dot (7.44 = intense copper blonde; .2 = pearl/iridescent, .7 = violet); Topchic uses a letter after the level (7N = medium natural blonde). The level (1-10) stays the same; what changes when converting is how the reflect is written.

Common questions when converting between these brands

Of the 58 Color System shades, 37 have an exact equivalent in Topchic, 5 close, 15 approximate and 1 with no direct equivalent. The level (1-10) is universal; what varies is the reflect.

No. Equivalences are approximate because each brand uses different pigments, bases, and concentrations. The level (1-10) is universal, but the reflect result may vary. We always recommend doing a strand test when switching brands.

Yes. Inside Blendsor you'll find it in Learn → Brand converter and in the chat attach button (+). There the equivalent comes with its confidence level and a warning if the product type changes, and you can send it to the advisor to fine-tune it for your client's base, grays and porosity. Download the app.

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.
