Yes, definitely not an object, and it is quite small (25kb gui exe  
unzipped).
So far you can:
1) load a image to harvest from (can just harvest directly or use #2 too)
2) load an exclusion image (any colors in it which are in the source image  
will not be output)
3) use RGB/BRG/etc..
4) dump a single (povray incompatible) XML color file
5) dump the same data but broken up into 256 length color_maps (in include  
file [can make it dump pigment maps and textures too]) until all  
non-duplicate colors are exhausted
6) supports RGB/RGBF/RGBT/RGBFT
7) a number of varying color range conditionals
8) a few ways to adjust filter and transmit based on the input data
9) adjust the [0.0 ... part of the color map based on percent of input  
image the color makes up
10) multithreaded..I hate apps which lock the UI...grr..

more...

Not bad for an hour of work so far...man I love .NET. ;)

I will add some other stuff before I release it, so maybe in a day or so  
(after polishing, proper error handling, etc.. small stuff) it will be  
ready.

That 256 limit for color_maps really sucks..it makes certain things (like  
#9) not as representatively accurate as they could be..
