Both mean 'various, all sorts of', but is there some subtle difference or not?

What is the difference between いろいろ and もろもろ
There are some grammatical differences.
[色々](http://dic.yahoo.co.jp/dsearch?enc=UTF-8&p=%E3%81%84%E3%82%8D%E3%81%84%E3%82%8D&dtype=0&dname=0ss&stype=1&pagenum=1&index=101315900000)
can be used as a na-adjective, but
[諸々](http://dic.yahoo.co.jp/dsearch?enc=UTF-8&p=%E3%82%82%E3%82%8D%E3%82%82%E3%82%8D&dtype=0&dname=0ss&stype=1&pagenum=1&index=119513200000)
is used only as a noun. So we say 色々な but 諸々の. (We can also say 色々の, but it is
less common than 色々な.) In addition, 色々 can be used also as an adverb.

Other than these grammatical differences, 諸々 sounds more formal than 色々 to me
when used in contexts other than fixed phrases such as その他諸々.

answer
In addition to Tsuyoshi Ito's point, I have the intuition such that both mean
there is a list of things, and `もろもろ` means that the things in the list vary
widely whereas `いろいろ` does not have such connotation.
