akatsuki symbol

It’s days like this I wonder…

Why do the Akatsuki members have different colored nails? Who chooses the colors? Do they choose their own colors? Why did Hidan pick dark jade green when it doesn’t really suit him as a color? Why do a lot of members pick colors that don’t match their over all scheme? Did Pein just order this and wanted to be the most flamboyant organization ever? I have a lot of questions.
