Question? About photo-paint?

Can I copy or scan in a picture of art into photo-paint and then break it down? Like change the colors... I seen in one forum where " Jef " I think wrote change color pallet to pantone r solid. Yet I still can not figure it out... Also, Is there a way to do simulated process with a picture/drawing?

Ok I went to a seminar which kinda broke things down to do simulated process, but in adobe photoshop... This is to create a channel in photoshop ...      1) create color pallet   2) then Select+ Color Range+ Sample color ... Ok this is as fast as I could write it down... Can anyone Convert this PHOTOSHOP language to Corel Photo-Paint language....
