PHOTOSHOP: Posterize a Color Gradient isn't evenly spaced

Created a linear gradient from White to 100% Cyan to Black. Tried to posterize into 21 linear steps. Did not work. Got extra steps of different colors.

You didn't set the gradient smoothness to zero, so you got a spline interpolated gradient that appears smooth, but is not mathematically evenly spaced. To get a linearly interpolated gradient (mathematically even steps, even with visual artifacts) set the gradient smoothness to zero.

Also, posterize will work per channel - but you interpolated multiple colors and will get even steps per channel in the gradient, which probably isn't what you want.
