It's a custom theme (it shows up when I do M-x customize-themes).  They
include a "color theme" version as well, but I'm not using it.

This is a simpler test:

(let ((cyan "#2aa198") (white "#ffffff"))
  (setq header-line-format
        (propertize
         "abcdefghijklmnopqrstuvwxyz"
         'face `(:foreground ,cyan :background ,white))))
         
It displays cyan text on white when I select any custom theme other than
solarized, tsdh-dark or tsdh-light (the latter two are bundled with
Emacs, I think) and white text on cyan background when I select one of
those.

Cheers.
