Colortemplate Variant: 0

[habamax]

We need a way to declare templates for 'no color' support aka Variant: 0.

See https://github.com/vim/colorschemes/pull/73

The current way is to use Variant: 2 (see my reply at https://github.com/vim/colorschemes/pull/73). Variant: 1 also works. For some reason, Variant: 0 gives an error. I'll look into it.

Perhaps, using Variant: 2 for “no color” was not the best idea. I will address that in Colortemplate v3.

So we can use either Variant: 1 or Variant: 2 for this.

I think that the value 2 is because when t_Co is less than or equal than two, Vim uses term highlighting instead of cterm. If this is inaccurate or you think this can be improved, feel free to open an issue in Colortemplate's repo.

I can definitely see colors with :let &t_Co = 2:

They disappear with 1 and 0, though.

Variant: 2 works for t_Co=0, I have just double checked here with my colorschemes.

I opened an issue at colortemplate's: https://github.com/lifepillar/vim-colortemplate/issues/53

The current Colortemplate's master supports Variant: 0 for b/w (term attributes), while Variant: 2 now uses cterm attributes.
