Here is a photograph:

By using the "Convert To Indexed" tool in the Image menu I created this:

I used 8 colours, Use current palette and Floyd-Steinberg options. I changed the default settings to use Separate/Split error propagation with a propagation value of 90.
To see the above images in all their glory you will need to click them to view them at 100%. As you can see from the results, although only 8 colours have been used, mtPaint has been able to blend the coloured pixels well enough to capture the essence of the original colours.
A related technique is stippling, where only 2 shades are used. This is most commonly done with a black ink pen on a white page. This can be done in mtPaint as you can see from this image:

I achieved this by loading the original JPEG, moving the white palette colour 7 to position 1 (hold the shift key, left click the white colour 7, and drag it to position 1 and then release the left mouse button), and then doing the same steps as above, but having only 2 colours in the final image.
To learn more about the specific options in the "Convert To Indexed" window, see section 6.8 of the mtPaint handbook.
