Which Colour do you use to show land?
The colour white is used to show barren land on topographical sheets.
What is the Colour code used to represent the land cover and land use in maps?
The Black-White Codes At times, planners use monochrome colors for land mapping and to differentiate land use categories. While the hatched patterns indicate denser land uses with heavier patterns, open space or recreational areas are left blank or lightly patterned.
Why do we use different Colours in land maps?
Usually, development authorities use land maps in which they use different colours to notify the usage pattern. These colours are used for graphically displaying land uses, roads, public infrastructure, and community facilities.

When sunlight strikes objects, certain wavelengths are absorbed and others are reflected or emitted.
