**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

1. Open the **Kanban** edit view in **Jestor**.
2. Find the conditionals section, where colour rules sit alongside displayed-field and open-card rules.
3. Create a colour conditional and set the rule it depends on.
4. Combine it with displayed-field conditionals so the relevant detail appears on highlighted cards.
5. 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.

## Frequently Asked Questions

### Does someone need to flag cards manually?

### Can indicators use conditional colour too?

Yes, on both the value and the background.

### Can I combine colour and field conditionals?

Yes, they are configured in the same section.
