Leaf Shinobi vest colours


I am curious to know why some leaf shinobi's vest colours are green and some
are dark green. For example, Shikaku wears a dark green vest and Kakashi wears
green. Are dark green vests considered elite shinobi? Wouldn't Kakashi be
considered elite? Does it signify something about that particular shinobi?

Thanks




I did a little bit of search about outfits in Naruto series, only 2 ninjas had
a dark green outfit.

[Shikaku](http://naruto.wikia.com/wiki/Shikaku) and
[Asuma](http://naruto.wikia.com/wiki/Asuma_Sarutobi). If you check both of
their profiles in Naruto wikia, nothing is being said about the color.

This is a peace from Asuma description:

> _His clothing consisted of the
> standard[Konoha](http://naruto.wikia.com/wiki/Konohagakure) ninja uniform
> with the sleeves rolled up half way, flak jacket, regular shinobi sandals
> and forehead protector. He also wore a sash that had the kanji for "Fire"
> (火) marked on it around his waist, a pair of black bangles, and bandages
> wrapped around the arms of his sleeves._

Also [the flak jacket](http://naruto.wikia.com/wiki/Flak_Jacket), for
[Konohagakure](http://naruto.wikia.com/wiki/Konohagakure) it's only one, there
is no other jacket that the [Jōnins](http://naruto.wikia.com/wiki/J%C5%8Dnin)
wear.

So I asume it has to do mostly with Shikaku that he was the [Jōnin
Commander](http://naruto.wikia.com/wiki/J%C5%8Dnin_Commander), so we can
understand the difference between him and the other
[Jōnins](http://naruto.wikia.com/wiki/J%C5%8Dnin).

So to summarize, it's just a speculation about all this. But there are no
evidence about these colours. Maybe in a Naruto SBS there is an explanation,
about this, which I can't find.
