How are shadows formed? In Peter Pan by J. M. Barrie, Peter loses his shadow when Nana the dog grabs it as Peter escapes out a window. Finding the shadow, Nana’s owner, Mrs. Darling, rolls it up and puts it in a drawer for safekeeping. Real shadows are more ephemeral. Try to grab a shadow, and your hand will simply pass into its shade. Try to jump on your own shadow, and it jumps with you, ever connected to your feet.
Bright yellow flames on the birthday candles studding an iced cake. Dusky blue flames circling the burner of a gas stove. Dancing yellow-orange flames crackling over wood in the fireplace, with flashes of red, green, and blue. Fire comes in a rainbow of colors, some rarely seen outside a science lab.
On a sunny day, the sky is blue, the clouds white, and the Sun a normal, if a bit boring, yellowish-white. But at sunset, white clouds and blue sky turn pink and orange and purple, and the Sun glows orange red.
