I cannot imagine anything worse! Why give yourself extra work because you will not like it!!! Paint it Pointing or Cornforth White both F and B and add orange towels. These colours would be relaxing and serene and you won't be repainting over a very difficult colour.
start with one ... send me a photo and I will magically paint the other walls on the photo and you can make an informed choice then ! or if you already have a tester on the walls send me a pic with the tester patch showed ! my email is on Houzz or possibly on my profile page here ?( maybe ?! - not sure !)
