ffffff

ffffff commonly refers to the six-digit hexadecimal color code for white in the RGB color model. In this system, colors are defined by two-digit hexadecimal values for red, green, and blue, each ranging from 00 to FF (0 to 255). When all three components are at their maximum (FF), the resulting color is white.

The value is typically written with a leading hash in web contexts, as #FFFFFF or using the shorthand #FFF for white. Hex values are case-insensitive in most software, so ffffff, FFFFFF, and FfFFFF represent the same color. In addition to CSS and HTML, hex color codes are widely used in graphics programs, design tools, and many programming environments. Some modern CSS implementations also support an eight-digit hex format that includes alpha transparency, such as #RRGGBBAA, where AA encodes the opacity.

In practical terms, white serves as a background color, a text color choice for dark-on-light contrast, and a baseline in branding and interface design. In printing, white is generally the absence of ink on the substrate, contrasting with the additive nature of screen-based white created by light. Designers must consider accessibility and contrast when placing white against other colors to ensure legibility.

Overall, ffffff is the standard digital representation of white in RGB-based color systems, widely recognized across computing, design, and media production.
