Hover over the color wheel to view color values.
Click to choose a web-smart color.
Just hover your mouse pointer over the color wheel and its values will appear below, you will see three values of the color from the wheel, web-safe, web-smart and unsafe.
Web-safe colors were used when monitors could only handle 256 colors, these days monitors can handle thousands and millons of colors, which allows the color wheel to give us a choice of
4096 colors. If an old monitor is used and you chose a web-smart color from the color wheel then it will gracefully show the closest web-safe color
Why should you use web-smart colors?
By choosing a web-smart color from the color wheel you are giving your design the best possible chance to show the same colors across all display devices.
