use numpy simply alot the class 255 pixel value in all 3 channel. I guess you are using opencv or something to display image in python that's the issue please read about proper display or saving image

Firstly, check if the pixel values of the image are 0 or 255. If that's ok, add (cmap='gray') to your show/imshow code line. e.g., plt.imshow(image, cmap='gray')
