What Does Browser-Safe Palette Mean?
The browser-safe palette is (was) a series of colors used in Web development. The palette was the original 216 standard colors displayed uniformly across Internet Explorer, Netscape and Mosaic. The colors are not based on aesthetics or beauty, but rather on mathematics.
The palette has 216 colors out of the possible 256, because these were the common colors used in the Mac and PC. The other 40 colors were reserved for OS use and varied in appearance. The object was to allow users of both platforms to observe the same coloration on any given website. While the browsersafe palette was important at one time, it is not relevant for modern web-design.
This term is also known as the 216 palette, Web palette or Netscape palette.
