Modifications to Using Color Swatches to Color ScrapSimple Templates for Photoshop Elements 11.
You can add a custom color swatch in Elements 11 pretty much the same way as you would in Photoshop, as described in the June 4th Newsletter article Using Color Swatches to Color ScrapSimple Templates. There is a slight menu difference, however.

The other difference, of course, is that we don’t have Color Overlays in Elements. The most similar way to color the ScrapSimple paper templates that I’ve found is by adding a solid color layer above the template, then clipping and blending it to the template as described in the tutorial on Coloring Patterned Ribbon Templates or by using Solid Color Adjustment Layers described elsewhere, for example in the Add An Autumn Glow to your Fall Digital Scrapbook Pages tutorial.
I hope this helps the Elements scrappers to use Monica’s fine tutorial!
