After she built her spectrum we chose the ones that stood out the most if we closed our eyes and opened them. Which ones did we see first? Our first lesson in warm and cool colors. It was a concept I did not understand even after years of illustration, until I started painting outdoors. I would look at the illustrations I loved and not understand why the whole scene worked for me...how the trees receded in the distance, etc. I know my granddaughter has a grip on something already that took me over 50 years to learn. And I will never look at a small rock the same way again.
Now I just need to do the same thing with my neighbors collection of beach glass.
