Yes, Evil is the culprit in a way. Here is the relevant code:

    (defcustom evil-default-cursor
      (list (or (frame-parameter nil 'cursor-color) "black") t)
      ...

Which is correct (and keep in mind black is also emacs' default color),
but is only evaluated once.

As a workaround: 

   Load the theme before you load evil (not just before enabling!).

or

   Set `evil-default-cursor' yourself (Here[1] is a truly evil cursor function).

For a less makeshift version I'd suggest either

1) change the default value of `evil-default-cursor' to nil and evaluate
   the code above instead always if `evil-default-cursor' is nil

2) advise load-theme and update `evil-default-cursor'

But 2. would only fix color themes.

What do you think? Frank? Vegard?
