The best choice for interior walls will depend partially on personal preference and on what other visual elements will be in the space. That said, some popular choices include Alabaster by Sherwin-Williams, Simply White by Benjamin Moore, and Decorator's White by Benjamin Moore. Each of these can provide a clean and crisp look that complements various decor styles and lighting conditions.

For a warm, calming white, you’ll need paint with undertones of red, orange, or yellow. If you don’t want yellow undertones, try Pompeii from Benjamin Moore, Snowbound from Sherwin-Williams, or Pointing from Farrow & Ball. 

A strong contender in this category is White Dove by Benjamin Moore. This soft, creamy color has warm undertones that make it suitable for both traditional and contemporary aesthetics, pairing well with a wide range of colors and lighting conditions.

That distinction goes to Stirabout by Farrow & Ball. This earthy tone is inspired by the nurturing porridge served for centuries in Ireland. It’s perfect for adding a warm and relaxed feel to any space.
