Nord colors for org habits consistency graph

[JonathanReeve]

Some themes use theme colors for the org habits consistency graph (in the org agenda view), which is a lot more pleasant than seeing theme colors everywhere, but bright red, bright yellow, etc, in the habits graph. I imagine this is as simple as linking four or five color names together, and would be a big improvement for me and others that use org mode.

For instance, here is how the gotham theme does it: https://github.com/wasamasa/gotham-theme/blob/master/gotham-theme.el#L931

If someone is looking for a quick setup, here is my implementation:

(custom-set-faces
 '(org-habit-alert-face ((t (:background "#3C4251" :foreground "#94BECE"))))
 '(org-habit-alert-future-face ((t (:background "#3C4251"))))
 '(org-habit-clear-face ((t (:background "black"))))
 '(org-habit-clear-future-face ((t (:background "#3C4251"))))
 '(org-habit-overdue-face ((t (:background "#454C5C" :foreground "#B3666C"))))
 '(org-habit-overdue-future-face ((t (:background "#4E5668"))))
 '(org-habit-ready-face ((t (:background "#3C4251" :foreground "#A8BD91")))))
