False color composite — schematic repeated. The display gun mapping again: 4 → Red gun, 3 → Green gun, 2 → Blue gun.

• Mnemonic: “NIR goes red, red goes green, green goes blue.” (Each band shifts one slot toward the longer-wavelength display primary.)
• Useful check when you open imagery: if vegetation is bright red, you’re looking at a false-color (CIR) composite.
