12BS Ultra-Blonde Beige Silver

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, 36 exact, 43 close and 28 approximate in this chart with Color System. For example, Topchic's 6N maps to Color System's 6. Natural reflects cross over best; matte ones need more adjustment. 2 shades have no direct equivalent in Color System; those cases need a formula adjustment, not a code swap.

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

Of the 109 Topchic shades, 36 have an exact equivalent in Color System, 43 close, 28 approximate and 2 with no direct equivalent. The level (1-10) is universal; what varies is the reflect.

Are brand equivalences exact?

Is the converter also in the app?

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.

Can I mix hair color from different brands?

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.
