Let's put together the colors of summer. Take a blue piece (the color of a summer sky). Then pick an orange piece (for the bright sun shining in the summer sky). Take a black piece as well (because sometimes in summer there are big storms with lightning and thunder, and then the sky darkens to black). Now pick a green piece (for the now very green grass and leaves, and the thick, full foliage of the trees). Lastly, take a red piece (for June poppy flowers, ripe cherries, refreshing watermelons, and sun-sweet tomatoes).
Arrange the five pieces in a row, touch them, smell their scents, and feel their touch-readable symbols: blue, orange, black, green, red.
