i just stumbled into what SS has in Spectrum, where u sort images in shades of the spectrum , in case one needs to match one's publication or page with a certain color.
but i also found this one, which is just as awesome,
especially when one of the images there is mine.

if u r a buyers, i like to know if u use this? i ask because i wonder if knowing that these whatucallit???
color sorters??? is part of your criteria to finding our images. if so, maybe this, along with keywords,
is yet another factor one should consider. as already we know certain colours tend to be favoured as you peruse the top selling images.

still, it's something i can play with on a rainy day
