Is it possible to detect pixels color with python?

I am trying to detect an exact pixel by its color, and then do something whether that pixel is being found or not. I think you (obviously) cannot make this with vanilla python, but I have not found any module in order to do this. If this is possible, I'd like to get some examples. Thanks in advice.

Edit: Basically, I need to scan a pixel (1920x1080 screen) and get the RGB Values

You can use numpy and pyautogui:

import numpy as np
import pyautogui

image = np.array(pyautogui.screenshot())

np.argwhere(image == [255, 255, 255])

It will return all points who are of the specified color.

You can use Pillow to do what you want.

You can try the following function. It's a modified version of the code from https://stackoverflow.com/a/765774/8581025.

from PIL import Image

def detect_color(rgb, filename):
    img = Image.open(filename)
    img = img.convert('RGBA')
    data = img.getdata()

    for item in data:
        if item[0] == rgb[0] and item[1] == rgb[1] and item[2] == rgb[2]:
            return True
    return False

For example, if you want to know if there is a red pixel (255, 0, 0) in example.png file in the current working directory, you can use the following code.

detect_color((255, 0, 0), 'example.png')  # returns True if there is a red pixel, False otherwise.

For getting a pixel color at specific coordinate, you can refer Get pixel's RGB using PIL.
