Hi hoping for help please. I have new narrow rectangular build on two levels externally clad in black with black joinery, ground level grey polished concrete floors and need help with all ceiling and external underside soffit white please (outrigger of 1 metre on each floor to provide shade) - I wasn't keen on white ceilings but as they continue to the soffit outside, i think i need to concede. I really don't want a yellowy , green or brown white.

I think a very white white would go but would appreciate some advice please

Thank you!

Fay
