Web safe colors
In the past, computer monitors were only capable of displaying up to 256 of the 16 million available colors. Therefore, a list of 216 web safe colors was created so developers could know what colors would be compatible with all types of displays.
Today, all modern display devices support millions of colors and web safe colors are not as important. For reference purposes, we've listed all 216 web safe colors in the below chart. Each of the color pages listed on our page also mention if the color is a web safe color.
