A couple of helpful YouTube Videos and a Freebie

https://www.youtube.com/watch?v=XsW73FjvVIg Shows a, short time, free download that will work with Photoshop Elements and I do believe Photoshop also. Worth taking a look at.
This one I really like; it is explaining a color wheel on Adobe. It will work with any program I should think. It is more of a resource item. If you go to the end of the video he will tell you the web site, but it is also listed under show more under the date of the clip.
