When to Use Colour Tagging (Multi-Deck Setup)

Colour tagging is especially helpful when you’re running multi-market or multi-language concept tests and have separate stimulus decks for each group.

It’s ideal when:

  • You have multiple decks (e.g. English, French) with the same concepts presented in each
  • Each slide shows one concept, with consistent colour tags across all versions
  • Participant videos are recorded while they view the matching deck

This setup allows CoLoop to accurately identify concepts across different markets—even if the deck content is translated—by relying on consistent colour cues.
