Instructions
Turn your computer on and open up Adobe Photoshop CS5 or Elements on your computer. Click "File" in the navigation bar and select "Open" from the drop-down menu. Use your computer's cursor to navigate to the image you want to colorize. Click the file and the "OK" button located in the bottom right of the window to open the image.
Click "Layer" in the navigation bar and select "Background Copy" from the drop-down menu. Click the "Brush Tool" in the margin on the left side of the program window to select this tool.
Change the "Mode" setting in the toolbar to "Overlay" and change the "Opacity" setting to the 35 to 45 percent range. This changes the intensity of the color that is being added to the picture.
Click the colored boxes in the bottom of the left margin. A color palette will open up in a new window. Use your cursor to select the first pastel color you want to paint with.
Click and hold your computer mouse to add the color to the regions of the image you want to paint. When done with this color, select a new color and repeat the process until your picture is completed.
Click "Layer" and select "Flatten Image" from the drop-down menu. Give your edited picture a new name and save it to your computer's hard drive.
