Here the author explains the use of the Photoshop CS6 eyedropper tool in detail through concrete examples.

1. Quick and accurate sampling of colors

Using the Eyedropper tool, you can draw a certain color from the image,

Or, the color is sampled with the average color around the pickup point, which changes the foreground or background color.

(1) Execute "file" → "open" command, the material "apparel advertising. tif" File open.

(1) First execute "file" → "open" command, the material "character line draft. tif" File open.

Tip: To enable designers to put their energies all on the drawing, Photoshop provides users with shortcuts to switch between the brushes and the eyedropper tools.

(4) and then activate the "character 1.tif" file, with the press key,

Click to set the sampling point again in the facial light area of character 1.

In the dialog box, select the "Red", "green", "blue" channels,

and adjust the RGB value by dragging the middle-tone slider.
