Replacing one color with another in NSImage

I have NSImage and want to replace one color with another (for example, replace blue with green) Is there an easy way to do this, and if not, how can I get this functionality?

This task is for the main image. Or you can use Quartz Composer to define an image filter and embed a QCView in your application.
