As well as contour lines, the Discovery Series of maps also use colour and shading to tell us how high the ground is above sea level.

The higher the ground rises, the darker the colour gets.

The green colour is very low ground, next is pale yellow, then there are roughly three shades of brown. The darker the brown, the higher the elevation of the ground above sea level .
