Colour formulas

Updated on 2026-08-22

Colour formulas are the data the client record exists for. That is why they sit at the front of the tabs, across the full width, in a fixed-width font — illum 30gr 6/ + 20vol has to be readable from a printout next to the colour bowl, not only on a screen.

Where do I find them?

Open the client record (Klanten → Klanten (Clients → Clients), click a row) and pick the Kleurformules (colour formulas) tab.

You also see the latest formula in two other places, without opening the record:

• on a block in the calendar, when it is tall enough;
• in the detail window of an appointment, under Laatste kleurformule (latest colour formula).

Writing down a formula

1. Click Formule toevoegen (add formula).
2. Datum (date) — already set to today.
3. Door (by) — which staff member.
4. Formule — Schrijf ze op zoals je ze in het salon noteert. Eén regel per sectie. — write it down the way you write it in the salon. One line per section.

Only the formula itself is mandatory.

Write it the way you always write it

HairConnect tries to parse your note into sections, brand, product, grams and developer. If that works, it is shown neatly per section. If it doesn't, it appears literally as you wrote it, with the label ruwe notitie — niet ontleed (raw note — not parsed) underneath.

Our interpretation is an aid. Your note is the source. The raw text is never thrown away or overwritten.

So you don't have to adapt to the software.

The list

Newest at the top. Per row: Datum (date), Formule and Door (by). You can Bewerken (edit) or Verwijderen (delete) a formula.

If there is nothing yet: Nog geen kleurformule — Noteer de formule van deze klant, dan staat ze bij het volgende bezoek klaar. — no colour formula yet — write down this client's formula and it will be ready at the next visit.

What the client sees

In the customer portal there is a My colour tab, showing per visit a colour swatch, the date, who did it, and a summary in plain language. Your raw note sits collapsed there under Stylist’s note, with the line Exactly as your stylist wrote it down.

At the bottom it reads: The swatches are an approximation, worked out from the level and tone in the note. The note itself stays the source.

See My colour in the portal.

Privacy

Colour formulas do not go into the audit log. They belong in one table, with one retention period — otherwise there are copies lying around that stay behind when a client asks to be erased.

They are part of the data export a client can pull from the portal themselves, both raw and parsed.

Frequently asked questions

Can a client change their own colour formula? No. The portal shows them; changing is only possible in the salon.

Where are the colour formulas from Optios? They came across with the import, in full, across all the years. They lived in the client pages there and not in an API — which is why the export fetches those pages separately.
