What free software will allow me to use Color Accent for PC?

I have the Canon Powershot SX100 IS and the Canon website says that it has Color Accent, but it doesn't. I emailed them and they said the site is wrong. I want to be able to take a picture I have and just accent the one color. Is there a free software that will do this?

A easy way to do this, if you don't know how to use photoshop is to use www.picnik.com , you just upload your image , then go to edit , and after that you go to create, and then you make the image black and white, and then you use the paint brush to select the areas you want in color.
