Like any camera in or out doors it depends on the lighting.
I always used a fixed white balance, never AWB. If it's florescent lighting try that, or play with the others, or even use custom and set it to what gives the look and feel you want.
If there are a lot of windows and it's bright outside try not to shoot at the windows. If you are using auto settings it may cause it to get to dark inside if you point it at a window. If it is set to manual ISO, and shutter speed and looks great inside as you point toward a window that is bright outside it will appear washed out.
I fly my Mavic Air in a Harley dealer last March.
Good luck with it.
