Purpose/Summary:  
The Natural Color RGB provides a false composite look at the surface. This RGB uses a shortwave, the near-infrared, and red channels from the instrument. 

Suggested Usage: 
Areas of water will appear blue, healthy green vegetation will appear as a bright green, urban areas in various shades of magenta, snow will appear as a bright blue/cyan, and bare soils being multicolor dependent on their makeup.

Note: Some agricultural fields are depicted as water, but are not considered flooded areas due to the crop type, which includes rice paddies. 

Satellite/Sensor: 
Landsat 8 Operational Land Imager (OLI); 30m resolution
