Colourmod is a widget that I use a lot while graphic designing.
You can pick a colour on the right and it shows you the Hex number, the cmyk value, the RGB value the Hue and saturation... everything you need to identify and correctly use this color again and again.
Also you can do it the other way around you can put the numbers in and a color will apear.
Very handy for designing websites or just altering your blog no need to go on the web or open a programma to find the number for your color just open your dashboard pick a color and there is all the information you might need!
