My Daggerheart campaign has been going for over 20 sessions. We use Roll20 and I wanted to add a border to their tokens to make them standout more. My idea, was to use the colors in the Daggerheart class symbols.

Colorful images of each class in Daggerheart including their domains.

I took these colors and created a gradient border in Photoshop for each character. Here's Barnacle, the Ribbit rogue.

Ribbit, one of the players in the Daggerheart Campaign. It is token shape with a gradient of colors on the border going from grey, to pink to purplish blue.
