This ongoing program runs from Friday, May 1, to Sunday, May 31. Hours are 10 a.m. to 4 p.m. Wednesdays to Sundays. What color is a tree trunk? Brown? Look closer. Is it just brown? How many different shades? For this self-guided activity, slow down and get close to nature. Notice all the color differences that add beautiful details to our world. Drop in during open hours to pick up a palette of nature shades. How many can you match to real objects outside? After your outside exploration, paint your own multi-hued masterpiece in the nature center and collect a prize.
