How to Use Colour Conditionals on Kanban Cards

Colour conditionals on Kanban cards change a card's appearance automatically when a rule is met. Risk, priority, and overdue work become visible without anyone tagging cards by hand.

Why manual highlighting fails

Any system that depends on someone remembering to flag a card will eventually stop reflecting reality.

Urgent items that were never marked urgent
Colour codes applied inconsistently across the team
Flags left on cards long after the situation changed
No visual signal at all on boards nobody maintains

What colour can communicate

Priority — high-priority cards standing out from the rest
Value — amounts above a threshold, highlighted automatically
Deadline risk — cards approaching or past their due date
Ownership — work assigned to a particular team or person
Stalled work — records sitting too long in one phase

How to configure it in Jestor

Open the Kanban edit view in Jestor.
Find the conditionals section, where colour rules sit alongside displayed-field and open-card rules.
Create a colour conditional and set the rule it depends on.
Combine it with displayed-field conditionals so the relevant detail appears on highlighted cards.
Apply the same idea to indicators, where conditional colour also changes with a reference value.

Why choose Jestor for visual process management?

Jestor applies conditional colour consistently across boards and dashboards, so a rule that marks something as at risk on a card can mark the same thing on an indicator.

Because rules read live field values, the colour updates as the record changes — nothing needs to be re-tagged.
