custom shadow for watch face

Hi, I've seen that on other devices (Samsung or Google watches, and many others), there are some cool watch faces with analog hands and outer shadows on the hands (for example, this watch face).

I've been wondering if a similar effect can be created in Monkey C as well (maybe using createColor with an alpha channel, BlendMode, or AlphaBlending options). I’ve tried many things, but the only "shadow" I managed to get was a copy of the hand with a constant color and full opacity.

Is it even possible? I am using the Venu 2 for my simulator.

Thank you in advance!
