I misunderstood your process. But after should work too.
Offer a chance to the user to increase by one pixel the size of a given colour region (like magic wand in photoshop or GIMP). So the user points his cursor onto a colour in the pattern and then selects "grow by one pixel". Then the connected region in that colour is simple increased by one.
But really it is all these annoying small issues that made me drop my old vector sticker maker program. One day I would like time to try again.
