I actually found Color Name & Hue, which claims to name 1,640 colors, and has a very convenient UI. I did go ahead and make myself a "chart" of all the colors on the Default Pallet, and attached it in case anyone else might find it useful. (Please let me know if there are any inaccuracies, I just used the names that website returned)
Out of curiosity, how does one go about creating a plugin? I know C++, Java, R, and (some) HTML, so I may be able to implement this myself? Feel free to let me know if that isn't feasible. I'll poke around the forum and see what I can find!
