Sorting Colors

Well, we've been wondering if he Silvan can sort colors. He lines up his cars occasionally, just to let us know he can do it, but besides that he does not seem to care very much for order or sorting things. So one night in early November we started sorting his duplos, and he continued flawlessly, until he had enough and with his "Schelm" on his shoulder he started mixing the colors (here he's adding a yellow one to the blue tower) - we all had so much fun :-)
