Custom bounding box colors by class

Hello everyone! I’ve just start toying around with Deepstream-app demos on object detection, Yolo and SSD.

My question is probably dumb: How can I attribute custom colors to detection bounding boxes based by class?

Thanks in advance!

Please check [primary-gie] config section:
bbox-border-color0=1;0;0;1
bbox-border-color1=0;1;1;1
bbox-border-color2=0;0;1;1
bbox-border-color3=0;1;0;1
bbox-border-color0: Colors for class 0
bbox-border-color1=0;1;1;1 : colors for class 1
