Black- Indicates Cultural (man-made) features such as buildings and roads, surveyed spot elevations, and all labels.

Red-Brown- The colors red and brown are combined to identify cultutal features, all relief features, non-surveyed spot elevations, such as contour lines on red-light readable maps.

Blue- identifies hydrography or water features such as lakes, swamps,rivers, and drainage.

Green- Identifies vegetation with military significance, such as woods, orchards, and vineyards

Brown- identifies all relief features and elevation, such as contours on older edition maps. and cultivated land on red-light readable maps.

Red- classifies cultural features, such as populated areas, main roads, and boundaries on older maps. 

Other - Occasionally other colors may be used to show special information. These are indicated in the marginal infomation as a rule.
