Decades ago I had one or two tẽte à tẽte about grayscale not being the same as black and white. You could emulate grayscale with b&w if you had a much larger canvas. In short: Black and white is 2 bits, grayscale is 8, 16 , more? bits

Am I wrong?

You're not wrong, Walter.

You are correct, grayscale is where every pixel's R = G = B, which for a 24 bit image would include 256 colors.

Black and white is 1-bit, where one value (say, 1) means white and the other (say, 0) means black.
