Depends. Chelsea in a north facing office would be wonderfully moody. But if moody isn't the mood you're looking to achieve then it's not a good move.

North light in our hemisphere is never direct into fenestration rather it sort of tumbles and stumbles in. As a result, various things can happen to the light beams along the way. Most common is the blue portion of the spectrum makes it way into the space more so than the other parts. Which is why many refer to north light as blue or cool.

While that may or may not be true in every case, it's pretty safe to say that beams of north light are overall well balanced with a tendency toward cool blue-ish-ness. And it is dim on a scale from dim to bright -- because it's not direct.

Dim qualities of light do well with saturated, midtone or darker color.

Chelsea or Hale Navy would play nicely into, and capitalize on the natural characteristics of north light. I'd say choose your mood. For example, moodily sophisticated Chelsea, or a classically understated and dignified navy.

Both equally appropriate for the function of an office.

You are so thoughtful to give such a detailed explanation. I am very grateful for your insight!

THANK YOU! :)

No problem. Good luck with everything.
