I've been looking through Tutorials and I keep running across the word "Desaturate." But everytime I do it's in a tutorial for Photoshop. I looked through the memories but I wasn't even sure what to look for cause I don't know what that is so if anyone can help me... I'm using PSP 8. I'd really appreciate it and if it's in the memories and I just didn't see it I'm very sorry.

EDIT: Thank you everyone who helped! I feel like a complete idiot that I didn't know that lol but thanx so much to all of you who helped. I really appreciate it. :D
