Color Coding
Color Coding is a way to fit more messages on the same board.
In this example, color coding allows for 36 symbols on the board, rather than 6.

This E-TRAN has 6 large colored boxes. Within each large box, there are 6 smaller cells. The colors and layout of the small cells are identical to the color and layout of the large boxes.

Note: Color coding is an advanced technique. Most children will never use it.
