Easter egg painting and pastel paint mixing

This is a work I normally have out from now (March) until the rest of the year.  During spring its' fun to add a white bottle of paint (in addition to the primary colors) to make spring colored pastels!  

Here's the colors all mixed up

Stirring them with a toothpick seems to work the best.  When stirred with a paintbrush the paint typically gets all stuck on the brush not leaving a lot left to paint with.  The small toothpick helps keep it neat as well.  There is a wet sponge on the tray that they can wipe the toothpick off between colors so they just need one.

Then they make whatever design they please!
