the reason white is 1 and black is 0 is because pixels are normally lights, so when white is displayed the light is lit, but is not lit when the colour black is displayed

This is gold for me, am trying to make a video player for an oled display who's resolution is just 128x64 pixels.

So Zeb and the Wizard set to work and took off the wheels and the top, and then they put the buggy edgewise, so it would take up the smallest space.

My answer to the question:
White in RGB is (255, 255, 255) and Black is (0, 0, 0) if we take the average we get 1 for white and 0 for black

Thank you
That was very straightforward and clear.
I wanted to ask why 3 bits is not 9, but 4 bits is 16. All number but 3 are raised to the power of 2. Is that correct?

Just one question. The positions:
Is 0, 0 at top or bottom?
