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:

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")))))

Thank you for your patience! 🙏🏼
It's been a while since I had free time to focus more on Nord, and my open source projects in general, and invest time in this issue due to work-life balance. Please keep in mind that maintainers must maintain (pun intended 😁) balance for their open source work and life to avoid burnouts so this gap in time has nothing to do with you or your contribution.

I recently published the first "Northern Post — The state and roadmap of Nord" announcement which includes all details about the plans and future of the Nord project, including the goal of catching up with the backlog. This issue is part of the backlog and therefore I want to triage and process it to get one step closer to a "clean state". Read the announcement about reaching the "clean" contribution triage state in Nord's discussions for more details about the goal.

Therefore it has been added for triage in the central and single-source-of-truth project board that is also described in more detail in the roadmap announcement.
