The Purest White on the Web

Screen calibration, color temperature settings, and ambient lighting all affect how white appears. A monitor set to a "warm" color profile (around 5000K) will make pure #FFFFFF appear yellowish, while "cool" settings (7500K+) can push it toward blue. Night-mode filters like f.lux also shift white to warmer tones. Use your display's built-in calibration tool or our full-screen white page to verify your screen renders true white accurately.

#FFFFFF is pure white in hexadecimal notation. This represents the maximum value (255) in all three RGB channels — red, green, and blue. It produces the brightest, most neutral white a screen can display. In CSS, you can also use the keyword "white" or the functions rgb(255, 255, 255) and hsl(0, 0%, 100%) — they all resolve to the same color.

Marketplaces like Amazon, eBay, and Etsy require pure white backgrounds (typically RGB 255,255,255) for product listings because it ensures visual consistency across millions of listings, eliminates distractions that could affect buying decisions, and makes it easier for their algorithms to process and categorize product images. It also creates the impression of a clean, trustworthy storefront.

Not exactly. Digital white (#FFFFFF) is an additive color — all three light channels at maximum brightness. Print white, in CMYK, is the absence of ink (0,0,0,0), meaning the paper itself provides the "white." The actual whiteness depends on the paper stock: coated paper appears brighter and bluer, while uncoated paper tends toward warmer, creamier tones. When designing for print, always factor in the paper's inherent color.

A white screen can serve as a large, diffused light source for portrait photography and macro shots. Open our full-screen white tool, maximize your monitor's brightness, and position your subject close to the screen. The large surface area produces soft, flattering light with minimal harsh shadows. This technique works especially well for product photography, food photography, and headshots when professional lighting isn't available.
