Grab mean color of screen in python instantly

meancolor.py

import mss
from PIL import Image, ImageStat
# From what monitor to take screenshot
monitor_index = 0


def get_color(rescale=(0, 0)):
    # Returns a list with the RGBA values.
    # Add a rescale tuple parameter (x,y) other than 0,0 to make faster calculations

    with mss.mss() as sct:
        # Grab raw pixels of the screen with sct.
        sct_img = sct.grab(sct.monitors[monitor_index])

        # Convert to PIL Image to resize it to a lower resolution for faster calculations.
        img = Image.frombytes("RGB", sct_img.size, sct_img.bgra, "raw", "BGRX")

        if rescale != (0, 0):
            img = img.resize(rescale)

        # Use the ImageStat module to get the mean value.
        return ImageStat.Stat(img).mean

Thanks to /u/tjarko from reddit for bringing ImageStat to my attention!
