Web-Safe Color Scheme (216 Colors)
The web-safe color palette consists of 216 colors formed by combining RGB hex values: 00, 33, 66, 99, CC, FF. Each color channel (Red, Green, Blue) uses these 6 values, creating 6×6×6 combinations. While modern browsers support millions of colors, these web-safe colors were essential in early web design when most displays could only show 256 colors simultaneously.
