1 Choose Edit > Preferences > General (Windows) or Photoshop > Preferences > General (Mac OS).
2 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.
