The value is always relative to the current tempurature, with "current" = 6500K. Repeating calls like ~redshift -O 5000~ will continue to darken the screen.

at night:
#+begin_src sh :results none
redshift -x
# redshift -O 1900K
# redshift -O 3700K
# redshift -O 5000K
redshift -O 6500K
# redshift -O 8500K
#+end_src

reset:
#+begin_src sh :results none
redshift -x
#+end_src

Supposedly using warmer temperatures will prevent eye strain. When setting it really low, I've found it only takes a  few minutes to get used to a new color tempurature.
