Gamma Doppler phases explained
Gamma Doppler has four phases and one gem. Each has its own paint index, so the phase is fixed when the knife drops.
Phase 1
Mostly dark, with green and black.
Phase 2
Mostly green, the closest numbered phase to an Emerald.
Phase 3
Green mixed with blue and black.
Phase 4
Green with blue-green tones, the bluest Gamma Doppler phase.
Emerald
Solid green. The Gamma Doppler's only gem.
How to tell which phase a Gamma Doppler is
Check the paint index. On knives, Phase 1 is 569, Phase 2 is 570, Phase 3 is 571, Phase 4 is 572 and Emerald is 568. Guns have their own block: Phase 1 1120, Phase 2 1121, Phase 3 1122, Phase 4 1123 and Emerald 1119. Phase-aware marketplaces show the phase in the listing title, and BO5's inspect servers show it in game.
