When choosing a picture which is very colorful and
picking 7th transf. you can see some artefacts on the
edge of two different colors - the other third appears.
Well, it's because the usage of 256 color pallete. You have to
predefine it at the start and cannot make any color you want.
Smooth transformation use the colors which are in the middle
of two others - that's why other colors appear sometimes.
There are two methods to avoid it - well, make a version that
impelements using higher depth of color :O) or use pictures
that are only shades of one color (like the start image -
shades of grey)
