Most toddlers, tykes and tots take delight in crafting crayon-created and/or Magic Marker-manipulated mini-masterpieces — the more abstract and over-the-top the better. If your little one wields a mean Crayola and is salivating to graduate to watercolors, charcoal or even acrylics, she or he will want to get artsy at the first installment of Tuesdays for Tots at Cheekwood Botanical Garden & Museum of Art’s Frist Learning Center. For this initial effort — called Color Craziness — the kiddies will reference the stunning glass sculptures of living legend Dale Chihuly to better understand how, for example, turquoise, yellow, brown and magenta can coalesce to yield a kaleidoscopic art form of which any 4-year-old can be proud. If you plan to bring to Cheekwood more than five rambunctious youngsters, you will need to call 353-9827 to give the museum folks time to brace themselves. Also, the little people should dress to make a mess.
