FYI - In photo-editing programs, e.g. Corel Photopaint, there are a couple of
ways to define regions or masks - shapes and colors.  Defining region
by color is easier (than by shape) if you want to do something like pick 
all the yellow spots on a butterfly's wings.  The shapes are defined
not by one color, but by a union of colors so that the regions would
not have to be of the same color.

So it seems that a standard way of defining regions is by both color and
shape.  The only problem with adding this 'color region' functionality to
the browser is that it's making the browser more and more like a graphics
program, and the functionality isn't strictly necessary (since by using
the same photo-editing program, shape coords can be generated by color
region or by hand).
