Hello, To change Kanban card colors based on a field value in Odoo, you can achieve this by using the Kanban's QWeb templates and adding custom CSS classes dynamically based on the field value. Here's a general guideline on how to implement this feature:

Define Field: Ensure you have a field in your model that will determine the color of the Kanban card. Let's assume this field is named color_field.

Create CSS Classes: Define CSS classes for each color you want to use in your Kanban view. For example, you can have classes like kanban-color-red, kanban-color-blue, etc.

Modify Kanban Template: Override the Kanban template in Odoo to include logic that dynamically sets the appropriate CSS class based on the color_field value.
