I would not use gray in an office environment. It is depressing.

Are the fluorescent lights putting out a "blue" light, or are they "soft" white? This will influence your choice of color - "cool" or " warm."

I notice that the windows do not all have the same trim color. If people need to be told to go to the office with the blue window or the orange window, it would save time.

What kind of business office is this?

There are some good Houzz newsletters on office colors for different professions.

Good luck!
