Instead of using the Adobe Color Picker, you
can choose colors from your computer operating system’s standard
color picker or from a third party color picker.
Choose Edit >
Preferences > General (Windows) or Photoshop >
Preferences > General (Mac OS).
Choose a color picker from the Color Picker menu, and
click OK.
For more information, see your operating system documentation.
Note: To
return to the Adobe Color Picker, choose it from the Color Picker
menu in the General Preferences.
