Feature: border color on priority?

Is there a way to add a color border to the todo’s?
I was thinking the admin could set different colors for different priority (ie. red for ‘DO NOW’) and for those that use priority, could quickly see in there list what’s what.

just discovered the color task button.
that just about solves my idea, but would like to set a color based on priority, or maybe an outline color instead of a full coloring.

task color could be different than priority task outline?

Currently there’s no way to set a color based on the priority, but maybe using the task color could work?

What would an outline color look like?

outline looks like this from kanboard

yes, task color is working, but having an outline based priority would be cool too.
