Why do I use the same colors over and over??? Must change. Must change!

After scanning some really soft acrylic-painted backgrounds,  I added brushes in Photoshop Elements.  I love, love brushes!  Can't get enough of them!  Then I played with layer styles.  These two use both overlay and hard light styles on their own layers. 

Here I used several Rhonna Farrer Vintage Photo2 brushes and added more color to the heart.  I really liked this light blue, which I found accidentally while playing digital color and brushes
