A Brief History of the Web Safe Palette
In the era of 8-bit displays, showing a color outside the shared 216-color palette forced browsers to dither - simulating the color with a noisy pattern of nearby colors. Designers stuck to the safe cube so logos and backgrounds rendered as solid color everywhere. Once 24-bit "true color" displays became standard in the early 2000s, the technical constraint disappeared.
Common Use Cases Today
