Christin here to share with you some ideas to add more color to your layers of paper. Sometimes when you feel like you don't have the right mix of colors or want to get that extra wowfeeling I have a suggestion to you. For this page I used a lot of colors on the background, but felt like I needed more colored layers.
Here I have painted three pieces of watercolor paper with watercolors. One in blue, one in yellow and one in hot pink to mix well with the papers chosen (I have worked with the Add-on kit and a few papers from the two Papern Pattern kits) You can get watercolor paper in very small book of paper for this. (Also added a golden heart from the main kit)
