CSS Color: White

White is the lightest possible color, representing all RGB channels at maximum (255, 255, 255). At hex `#FFFFFF`, it has 100% lightness with no hue or saturation.

In web design, White is the most common background color. It provides maximum contrast for text readability and creates a clean, spacious feel. White space (negative space) is a fundamental design principle that improves readability and visual hierarchy.

For accessibility, White provides maximum contrast against dark colors. Black text on White achieves the theoretical maximum of 21:1 contrast ratio. However, pure white backgrounds can cause eye strain in prolonged reading — many modern designs use off-white tones like `#FAFAFA` or Snow.

White pairs with every color. In modern web design, the trend is moving toward slightly off-white backgrounds (Ghost White, Snow, Ivory) for reduced eye strain while maintaining the clean aesthetic White provides. In Tailwind CSS, `white` is a built-in color.
