FWIW it doesn't work for shorthand color notation, e.g. #fff;Rickard Johansson wrote:Color hint under mouse cursor
To display a color hint move the mouse cursor over a color value in the text and wait a second. The hint is displayed until you move the mouse.
The hint display the color in a colored rectangle together with several color values in different formats.
The first value is an RGB() value. Next is a web color value e.g. #F2A723 and last a decimal value.
You may want to enhance the spectrum of recognized color formats (even though I don't see usefulness of color hint at all...); different formats are listed e.g. at this MDN page.
