First stage

Let's put together the colors of winter. Take a gray piece (for the sky in winter, when you can go for months without seeing the sun). Now take a black piece (for the bare trees, and their leafless branches silhouetted against the sky). Now pick a white piece (for the ground, the fields, the streets, often covered in snow or ice). And at last, take a red piece (for the flames in the fireplace, the warm blanket wrapped around you, and the warmth of your home, sheltering you while the wind blows outside).

Arrange the four pieces in a row, touch them, smell their scents, feel their touch-readable symbols: gray, black, white and red.
