...You can only assign one version of an icon to a folder. Dark color scheme is only supported for macOS 11.0 (and later) right now. Make sure the corner pixels of the mask image are transparent. They are used for empty margins.

...Manually lay a grid on top of each page to generate bounding boxes for characters (potentially replaceable by an automatic corner-detection algorithm). Generate a low-poly mask for each character on the grid, and save the thumbnails (using OpenCV). First, red channel is subtracted from the grayscale, in order to clean the annotations printed in red ink. Next, the image is thresholded and fed into the contour-tracing algorithm. A metric is then used to discard shapes that are unlikely to be part of the character in interest.
