Dunno. I'm really no expert on this. But IIUC `display-color-cells' gives info about the color depth / number of colors supported by the display. I was assuming that whatever the display supports Emacs would support too, but maybe that's a mistaken assumption. So I was assuming that `display-color-cells' would indicate the number of colors available (supported). Then, based on that I figured we should be able to know how many hex digits to use for each component. Maybe I'm wrong (it's beginning to sound like it), but that's how I was thinking. Again, I know nothing about this stuff. It's quite likely I'm confusing apples and oranges. Thanks to whoever clarifies this for me.
