The color picker in Photoshop is easily one of the most-used tools when you are creating original work. In CS6 the default color picker is a boring hue box. Some people prefer the box, but if you’re like me the hue wheel is so much more appealing. I’ll show you how to change it in just a few steps.
In Photoshop click the Edit tab on the menubar and select Preferences > General. You can also press Ctrl + K as a shortcut to open this.
In the General tab of preferences click the HUD Color Picker dropdown and select the Hue Wheel. There are 4 different sizes available and I prefer the small one as the others take up most of the screen. Press OK to save changes and exit.
Now just press Alt + Shift + Right-click (mouse) to open up the color wheel.
Incase you’re curious about the different sizes, I snapped a shot of each of them below. These screenshots are ordered from smallest to largest.
