Hexy
Colour picking with ease
It's a pain to have to select layers, highlight pieces of text, and open the Color Picker to simply grab the hex value of a particular color. Hexy allows you to use the Eyedropper tool to simply click on the color of the object you're after and copies it directly to your clipboard! Setting a new color as your foreground or background? Hexy will automatically copy that for you as well.
