View color information while adjusting color

1. Open an adjustment dialog box (under Image > Adjustments) or add an adjustment using the Adjustments panel.
2. As you make adjustments, view the before and after color values in the Info panel. Move the pointer over the image to view color values at the pointer location.
   Note: If you are using an adjustment dialog box, the Eyedropper tool is activated (and other tools temporarily disabled) when you move the pointer over the image. You still have access to the scroll controls and to the Hand and Zoom tools using keyboard shortcuts.
3. If you’ve placed color samplers on the image, the color values under the color samplers appear in the lower half of the Info panel. To add new color samplers, do one of the following:

   • If using the Adjustments panel, select the Color Sampler tool and click in the image, or select the Eyedropper tool and Shift-click in the image.

   • If using an adjustment dialog, Shift-click in the image.
