Floors Pictures Needed 
Grinding floor slabs to achieve a gray type terrazzo finish creates a visual texture that fits well with the cut stone bevel edged walls. A gloss or semi gloss sealer provides a deep lustrous finish. Even easier, the floors may be acid stained before the wall panels are installed to eliminate the need for masking. 
 
The semi uniformity of color allows the walls to be more colorful in staining applications if desired.
 
Walls
Casting interior wall panels with white Portland cement creates a marble like appearance. It's good to start with walls as white as possible. Once tinted, the only return back to white would be with paint. Any natural stone look would forever be eliminated with the first application of paint.
The brightness and reflectivity of white minimizes lighting needs, saving energy in the long run.
Walls can be sealed with a flat or semi -gloss sealer.
 
Ceiling
The ceiling is sprayed with drywall texture and knocked down to the preferred finish.

 

Exterior walls

Panels may be integrally dyed in the lightweight concrete and/or stained. I believe an inconspicuous camo finish using predominant site colors would be best. The south wall enclosed within the greenhouse should be as dark as possible to enhance solar absorption.
