Breakdown of the colors and their corresponding depth ranges on the Nav map. There are 5 water colors and land. In the chart below, 1 is the color (white) closest to land and 5 is the color (darkest blue) representing the deepest water.
0 = Land (0+ ft)
1 = 0-48 ft (white)
2 = 48-175 ft
3 = 175 - 490 ft
4 = 490 - 850 ft
5 = 850+ ft (dark blue)

As you can see, US boats are pretty safe diving in colors 3,4,5.
Knowing this may help resist the urge to use the depth sounder near enemy.
