Our kitchen has a beam that divides it where it was once two rooms (I think the other room was probably the mudroom). Yesterday we painted the section on one side of the beam. Today we are painting the second section.
Here is John washing the ceiling. It's never much fun working over your head on a ceiling.
We are painting the ceiling white, but not true white. The color we are using is called Marble White. It reads white but it is softer than true white. You can see the difference here as the Marble White gets rolled over the true white.

So if you have and old house and want to be historically accurate, stay away from true white. I do have an old house but I am not trying to be historically accurate. I just think true white is too stark.
