Original Photo

2. Select Polygonal Lasso Tool and apply feather about 5px (depend on the size of your photo). Since feather is applied, you do not need select the object you want to select precisely.

3. Select >> Inverse (Shift + Ctrl + I) and Image >> Adjustment >> Desaturate (Shift + Ctrl + U). Then the object you want to color will be in color with the background in black and white.
