Google has a special card that’s both a color picker and a color converter. For example, you can search for HEX color codes like #123456 and Google shows the color and converts it to other formats: RGB, HSV, HSL, CMYK. Google’s card also shows up when you search for RGB values like rgb(255,0,255). The most interesting feature of the card lets you pick a color interactively.
Other queries that trigger Google’s card: RGB to HEX, color picker.
This is not a new feature, but it’s worth pointing out that Chrome has its own color picker and converter in the developer tools. Click a color in the styles tab to open the color picker and shift-click a color to convert it to a different format.
