CPick is a software for getting colors from the screen with the built in color picker. By using the built in magnifier on your Windows 7 machine you can change the screen from one color to another by dragging and dropping colors on the screen. These are just a few examples of what this software does, there are many more tools available.
To use the CPick color picker, first download the software to your computer, if you do not have it already. It is important to have the latest version because it is a lot more up to date than older versions. Then open up CPick, it is a simple matter of selecting any file or folder and clicking on "open". You will be prompted with a series of parameters such as type, file name, width, height, alpha, blend mode, hue, saturation, and values. Use the parameters to choose the file you want to use as your palette, then click OK.
Once you are done customizing your palette, you can save your new color picker for future use, you will be asked to select which types of formats you want to save your palette in. Once you have saved your palette, it is time to use your CPick color picker. To use your CPick just simply click on the little "gear" icon that is on the left hand side of your screen.
