How do I find the dominant color in an image generated by PIL.image.crop()?

Question

I am trying to crop an image using PIL.image.crop() and then determine the most dominant color in the cropped image. I've tried using ColorThief but it will only analyze an image if a path to the image is specified, and I don't want to have to save a file to my device every time I run the program. Is there a way to find the dominant color without saving the cropped image to my device?

from PIL import Image

im = Image.open("C:/Users/nickr/Desktop/right.png")

im1 = im.crop((0, 0, 50, 50)) #gives top left grid cell
im1.show()


color_thief = ColorThief(im1) #this will not work because it is not a path

im1Color = color_thief.get_color(quality=1)
print(im1Color)
