How do you enchance the color ofone thing in a picture say eyes or lips using paintshop pro?

Are you talking about just colorizing one point of focus?





In Paintshop Pro - just duplicate the background layer and then render that layer Black %26amp; White (look for a desaturate option).





Then choose a soft brush and erase what you want colored (say the eyes).





This way the eyes from the colored layer below show through.





--- Edit ---





If you are looking to just enhance the color you'd perform similar steps by duplicating the background layer. Enhancing the color of the entire image.





Use the selection tool to create a quick selection around the item (lips) and select the inverse. Delete everything in the new selection.





use a soft edged eraser tool to fine tune the selection to create a nice blend.
