In using PanPastels, I came to realize that some of the colors change when they’re rubbed into polymer clay.  This isn’t surprising, but which ones?  

I made swatches of each color I had by rubbing the pastels into raw polymer. Then I baked them and sealed them with Translucent Liquid Sculpey thinned with Sculpey Clay Softener.   I’ve found this to be my favorite sealant for pastels. Then I photographed them on top of the corresponding pans of pastels. 

The lightest colors that turned darker are something to watch out for, in particular the lavender and light blue. Some of the darker colors came out lighter. Testing colors on raw clay before applying them is a good practice to avoid surprises. Also consider that rubbing them into the clay gives a darker result than applying them lightly with a brush.
