If 'Update Palettes' is checked, the colours used for the dither and the nearest colour images are written to the respective text boxes on the right, in decreasing order of area in the output image. (ie. most common colour first).
Select a palette using the drop-down on the right. Edit the palette by changing values in the Active palette text box, then click 'Generate...' to see the results.
