purewhite

Purewhite is a term used to describe a color perceived as white with full luminance and no perceptible hue. In color science, true white is the color point produced by combining light across the visible spectrum in roughly equal proportions; in digital systems that point is represented as RGB 255, 255, 255 and hex #FFFFFF, typically under a standard illuminant such as D65. The concept of purity here is relational rather than absolute, since white can shift with lighting and the surrounding colors.

In display and print contexts, pure white has practical implications. On screens, it corresponds to maximum channel values for all primaries, but actual perceived whiteness can vary with display technology, color management, and ambient lighting. In subtractive color systems like printing, white is the absence of ink; a white sheet of paper supplies the whiteness, and adding white ink is not standard practice except for special effects.

The term “PureWhite” or the stylized “purewhite” is also used as a brand name or product designation in various markets, including paints, cosmetics, and consumer electronics. Because there is no universal standard governing such a label, it does not denote a single, uniform product. In design practice, pure white offers high contrast and neutrality but can cause glare and reduce legibility under bright lighting; designers often use near-white or off-white alternatives to improve readability and reduce eye strain.

Overall, purewhite functions as both a descriptor of a high-luminance white and a marketable label, with meanings that vary by context and application.
