White

#ffffff is a perfectly neutral white, as it contains an equal balance of all primary light colors. Unlike off-white shades that may lean yellow or blue, this pure hex color creates zero color cast, allowing it to pair seamlessly with any other hue in your palette.

This shade provides the highest possible contrast ratio of 21:1 when paired with black text, making it the industry standard for ensuring legibility on screen. Using #ffffff as a background remains the safest way to meet WCAG contrast requirements for body copy and UI elements.
