Color Picker

I love digital painting and find the use of different colors fascinating. I have also been wanting to learn Qt for some time. This color picker is the child of those interests.

Clicking the "Pick Color" button enables color picking mode which uses a nearly invisible overlay widget to capture a PixMap of the screen. Colors are then extracted from the PixMap based on the current mouse location transformed into screen space. Clicking 'Enter' or pressing the left mouse button will select the current color while any other action will reset the picker to the previously picked color.
