#FFFFFF
CSS color
Overview
At full intensity on all three additive channels — rgb(255, 255, 255) — a display produces white, hex #FFFFFF. It is the brightest value in the RGB gamut and, like black, a neutral with zero saturation and no defined hue. White is one of the sixteen original HTML named colors and the conventional background of web pages and printed documents. In additive light it represents the combination of red, green, and blue at maximum, the opposite of black's total absence. Because it reflects across the visible spectrum, white carries the highest perceived luminance of any color and is used as a reference point for measuring contrast ratios against darker foregrounds.
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.

คุณสมบัติ
จิตวิทยาสี
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.
