how to outline object with different color ?

Hi!
i know there is a function called "set_outline color" in scene module ,however, this function will apply all outline anim with new color. in my task, i need to outline object with different color .
Any tips on where to start? Please help

Hi! Per-object outline color isn't supported right now. We have plans to improve the outlining algorithm in future. For now you can try to use the Glow effect. It has specific use cases. How properly it can emulate the outlining effect depends on the certain task/objects/scene configuration.
