Photoshop: Coloring Images
This tutorial teaches you how to change the colors of an image by painting them.Step 1
I will use this image of Koda Kumi.
Step 2
Make a new layer and place it above your image. Use the brush tool, select a default hard or soft (whichever you prefer) brush, zoom in, choose a foreground color, and start painting over the areas that you want to re-color.
Step 3
Now select the layer with your paint, and set it to color.
