I know there is an easy way to do this, but I can't figure it out, how
do I get the color of a pixel? I used the ImageGrab method and I want
to get the color of a specific pixel in that image. If you know how
to make it only grab that pixel, that would also be helpful.
Basically I'm trying to make a:
if pixel == color:
do_this()
else:
pass

And have it do this as fast as my pc can handle (that is why only
grabbing 1px would be helpful)

Try image.getpixel((x,y)) to retrieve the pixel at (x,y).

If the OP needs to access many pixels, then he can use the load()
method on the image object, and then read/write pixels (tuples of 3
ints) using getitem []

import Image
im = Image....
img = im.load()
img[x,y] = ...
.... = img[x,y]

I don't know why the image object itself can't have the __getitem__/
__setitem__

I got news for you. Orange Country is still California. Where did
you move from?

Sounds like you are an African American moved to Tanzania, Africa to
live for good.
Is that right?
