#FFFFFF

CSS color

White (#FFFFFF) is pure, maximum-luminosity white in the CSS standard — the complete combination of all visible light wavelengths, or the full output of all three RGB channels. As the theoretical complete reflection of all light, pure white has profound symbolic significance across cultures: purity, innocence, cleanliness, new beginnings, and in digital design, the blank canvas itself. In web and graphic design, pure white provides maximum contrast and the foundation of all light-background layouts.

色彩心理学

Near-whites and off-whites radiate purity, simplicity, and spacious clarity. They feel open and unbounded, associated with cleanliness, fresh starts, and minimalism. These tones create a sense of potential and possibility, inviting focus on content.

Design Usage

Off-whites are preferred over pure white for page backgrounds to reduce glare. They feel warmer while maintaining a clean, bright aesthetic. Use for primary backgrounds and content areas where visual breathing room is needed.
