Really, my favorite color is anything in this image.
I just love pale shades of blue-gray and blue-green. Anything on the dull column will do.
I definitely have more items in that color spectrum, but I only went through the first 100 pages or so. I have 185 pages of items, and I didn't have that much room to work with, as you can see. There were too many good items for me to make anything fancy or remotely good-looking, so...yeah.
