The short answer is yes, use the pen tool to select the area you want to color in - then use paintbrushs and other tools to change the look of your selected area.

 

Firstly u take one image/Pic
making of selection -> by using Lasso Tool/ Polygon Lasso Tool/ Magnetic/ Magic Wand Tool/ as well as "Pen Tool"
after the completion of selection part
use the masking tool for COLOR

goto that link :

 

use the pen tool to create a path around what you want.
then create a new layer mask
then you can right click the layer and go ot blending options choose a solid color or gradient

or you can use the pen tool to make a selection you can click the path layer and make a selection
then color in what you want with a paint brush. ctrl+B

or you can just use the lasso tool to make a selection and just use the brush tool to color it in.

 

As is true of many procedures in Photoshop, there are several ways of doing selective color. This is a quick and easy method.

First open your photo in PS of course.

Then go to Layer - Duplicate Layer

Click OK

Then go to Image - Adjustments - Hue / Saturation

Drag the Saturation slider all the way to the left to make the photo black and white.

Click OK

Then get the ERASER tool from the tool box on the left side of the screen. It is usually the next tool under the clone stamp tool. Just hover your mouse over the tool, and it will say Eraser.

When you have selected the Eraser, go up to the Brush options box at the top of the screen, and click on the downfacing arrow. Set the Hardness of the brush to 100% so you will have accurate control of selection. You may also need to raise or lower the brush size to suit.

Erase away any black and white from where you want the color to be revealed.

When done go to
Layer - Flatten Image

Then just do a Save As to wherever you want to save the photo.

hope this helps you
