Colour tagging is a unique CoLoop feature that enhances accuracy in concept testing by detecting visual cues in your stimulus deck. This guide walks you through setting up and using colour tagging in your project workflow.
Coloop’s colour tagging method is designed to enhance accuracy in concept testing by automatically identifying and tagging concepts during video analysis.
This method works best when participants are presented with a stimulus deck (containing one concept per slide) and videos featuring that deck are analysed.
To ensure effective concept tagging, follow these steps when creating your stimulus deck:One Concept Per Slide: Each slide should focus on a single concept, whether it’s an image or text.If you have more than once concept per slideplease see belowAdd a Distinct Colour Box:
Place a small colour box in one corner of the each slide.
The colour box must be unique from other elements on the slides to avoid confusion during analysis.
Use the same colour throughout the deck for all concepts.
Add the name of the concept inside the colour box, and make sure the concept name stays on a single line.
Be sure to present this deck during your interviews and confirm that the recording clearly captures the slides.
We strongly recommend having one concept per slide wherever possible.CoLoop cannot differentiate between multiple coloured boxes on one slide. Therefore, if any slides contain more than one concept you will need to follow these steps:
Label such slides under one title (e.g., “multi”) within your stimulus deck before uploading it into Coloop.
Add additional labels manually to the PDF once loaded into CoLoop in the files section. Open the PDF and edit concept labels. Press submit when ready to confirm labels.CoLoop will automatically apply all the labels you assign to the slide to any relevant sections while that slide is onscreen. You can review and edit these labels afterward if needed.
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.
