The D/T grid is also known as the 'Fizzy grid'[1] and it is a matrix with all the 81 possible D/T-combinations a geocache can have. Similar to the 366 grid the color of the cell of each grid changes as the number of the cell increases. At Project-GC the "final color" is red[2] and this will be the color of the highest number on the grid, the other cells of the grid change with every found on the grid and are relative to the scale between green[3] and red.
