Posterizing B&W into colour

I believe I once had a free photoshop application which would 1) turn a black and white images into an image using a limitied pallette a few different shades of grey (resulting in sharp divisions betweeen the shades) and then 2) one could ascribe a different colour to each of those hues. (this was quite easy in the days of Deluxe Paint.)

It may have been two separate plug-ins. I believe the computer-name for the first step (sometimes called colourization) is quantizing.

Not sure about the next step.

Thanks for any suggestions.

(Incidentally, I'm using this in Mirage, not photoshop, so photoshop's on-board filters aren't available.)
