What is the difference between a pure white and an off-white paint?

Pure white paint is formulated with minimal tinting pigments, yielding a high Light Reflectance Value (LRV) typically above 90, making it highly luminous and ideal for ceilings. Off-white paint contains small amounts of yellow, red, brown, or grey pigments, creating subtle undertones that soften the color, reduce glare, and help the paint layer harmonize with residential lighting and flooring materials.
