use [pix_crop] for getting the specific region (rectangles only)
use [pix_mean_color] (CVS) for getting the average color of an image.
OR use [pix_resize 1 1] (CVS) to resize the image to 1 pixel and get the
value of that image with [pix_data] or [pix_dump]
OR convert the image to a signal and use [lop~]
