As cards pile up, you need a way to find your bearings. Coloured labels are the perfect tool for sorting and filtering in the blink of an eye.

What labels are for

• Categorising — by type (“Design”, “Copywriting”, “Urgent”).
• Prioritising — red for high priority, green for secondary.
• Filtering — show only the cards carrying a given label.

Each label has a colour and a name: the name makes it understandable even to someone seeing the board for the first time, and it improves accessibility too.

Best practice

Keep a small, consistent set of labels across the whole board. Too many colours destroy readability instead of improving it.

Key takeaway: one label = one colour + one meaning. Stay minimal and consistent.
