Change an Object's Color

Do it for me 1. Select the Magnetic Lasso tool .

The border of the magnetic lasso snaps to the edges of a selection. (You may want to use a different selection tool depending on the shape of the object you want to select.)

2. In the options bar, set the Feather radius to 1 pixel, and set the other tool options as desired.

Feather creates a soft-edges selection. Anti-alias smooths the jagged edges of a selection.

Width specifies detection width of the lasso, Edge Contrast specifies the lasso's sensitivity to edges, and Frequency specifies the rate at which the lasso sets fastening points.

Do it for me 3. Choose Layer > New Fill Layer > Solid Color to create a new layer.

5. Select the desired color in the Color Picker, and click OK.
