No :RainbowParenthesesColors available

[Jeansen]

I can only execute :RainbowParentheses. Vim tells me there is no :RainbowParenthesesColors (Not an editor command)

Well, I comment 2 years too late but it seems :RainbowParenthesesColors is only a usable command when rainbow-paretheses is active.

For me, it's not a command before I execute :RainbowParentheses, then it is, and after :RainbowParentheses! it is no more.
