Unhelpful default colors

[aclementev]

Hi!

I was trying today the plugin, and found that for some reason, the default colors picked suck for the
base16-atelier-dune colorscheme. Most of them look basically the same as the default text.

Here a capture of :RainbowParenthesesColors output:

Also, I am using terminal vim on Windows Terminal, with a base16 colorscheme with:

set background=dark
let base16colorspace=256
colorscheme base16-atelier-dune  " Same issue with base16-default-dark

that's true, it picks some colors that just disappear the parenthesis (invisible), better let user to pick a set of colors based on their own color scheme?
