Register of colour professionals
Since 1 August 2025 the Netherlands Colour Institute (SNKI) maintains the register of colour professionals, formerly the quality register of the BNK foundation. The register lists everyone who obtained the Colour Advice or Colour Design diploma and makes every registration verifiable by registration code.

Two register titles
Kleurkundige
Register title for the Colour Advice diploma (Dutch vocational level 3), obtained through the Kleurenschool programme Kleuradvies.
Register Kleurvormgever
Register title for the Colour Design diploma (Dutch vocational level 4), obtained through the Kleurenschool programme Kleurvormgeving.

How do you get listed?
Registration is tied to the diploma. Whoever completes the Kleuradvies or Kleurvormgeving programme is entered in the register; the exam and registration are part of the programme. Every registrant receives a registration code, which can be verified on this site. Registrations from the former BNK register remain valid.
Verification
Every diploma and certificate holder has a unique code, for example SNKI-K4-2018-0003. The verification page shows name, title, year and status straight away.
For registered professionals
Own page in the register
Registrants with a level 3 or level 4 diploma can extend their listing with their own page: a short text, a photo and a link to their website. € 75 per year (excl. VAT). The basic listing is and remains free.
Requests and questions: register@snki.nl.
Badge for registered professionals
Anyone listed in the register can place a "Registered colour professional" badge on their own website. The badge shows the registration code and links to the verification page. Find your badge by entering your own code on the verification page.
