Colorizing images is a very easy thing to do! They look really good, too!

First choose your image. I usually use a blend, but to make this easy I am starting with the image below of the space faerie.

All you need to do is open up your image into PSP8. Once you are ready to colorize, click on Adjust>>> Hue and Saturation>>> Colorize (as shown below) or just use type in shift-L.

A window will then pop up. There are two different pieces you can play with to get your color, Hue and Saturation. Hue determines your color and saturation determines the brillance of your color. Just play around with them until you find the color you are looking for. As you can see in the image below, I am going for a blue/green color.

Once you are done choosing your color, just click OK. Then save your image and viola!
