Shoji White has greige (gray and beige) and very mild green undertones. The green is nuanced enough that most of the time, you won’t even notice it’s there. But it IS there (and it can turn some people off).
Alabaster has the same creamy quality & subtle yellow undertones, but it appears much lighter than Shoji White. Alabaster is often cited as one of the favorite white paint colors by interior design experts.
