Using a simple homemade fingerpaint recipe we added beautiful Stockmar watercolor paint to achieve the colors we wanted. Here's a helpful hint... do not tell your 10 year old to go ahead and add the paint and then turn around in the kitchen or you may end up with no Stockmar paint left like me... only a small drop or two is really need but in any case...moving on..
After your fingerpaint solution is cool and in containers add your paint (a small amount not like us!) and mix, mix, mix.
Until you have your colors.
Then put on your aprons and find a bunch of little fingers..
Make rainbows with your fingers...
Sing songs about Leprechauns or not...
