I tried Colors for a while (and Pochade, and others), and the part they all suck at is the loupe. They all use that horrible, tiny, OS X default color picker.

I tried Colors for a while (and Pochade, and others), and the part they all suck at is the loupe. They all use that horrible, tiny, OS X default color picker. It barely magnifies things at all, and half the time the mouse pointer is still inside which makes it even harder to use. This app's loupe is pointer-free and customizably large. It's fantastic!
