Apple Pencil pen color is darker than the color given to PKInkingTool

Question

I've got the bare minimum apple pencil setup: a PKCanvasView named 'drawingView' given an inking tool as follows (to set the starting pen color):

let penColor = UIColor.white.withAlphaComponent(0.5)
drawingView.tool = PKInkingTool(.pen, color: penColor, width: 15)

However, when I use the pen, it is extremely dark (I've tried this with several colors besides .white). Is this a glitch interal to PencilKit that others are experiencing, or am I missing something?

thanks

Just realized the issue. Figure I might as well leave it up in case it proves useful to someone. PKCanvasView darkens its pen colors when the device is in dark mode. To override that, I set the following property of drawingView (my PKCanvasView):

drawingView.overrideUserInterfaceStyle = .light
