ColorPicker allows for the picking of colors through a simplified but precise tool.
This little Open Source color picker resides in the systray and comes with a minimal interface, but that doesn't detract from its usefulness in precisely picking colors and saving the values to the clipboard. There are limited configurations included, like the ability to change the cursor when actively picking colors. You can also change the activation hotkeys. You also have the option to change the color format between HEX, RGB, HSL, HSV, and VEC4.
ColorPicker is designed to be a simple and fast system-wide color picker that can pick colors from any currently running application.
