Phase 3
Green and blue, with less black than Phase 1.

How to tell which phase a Doppler is
Check the paint index. On knives, Phase 1 is 418 or 852, Phase 2 is 419 or 618 or 853, Phase 3 is 420 or 854, Phase 4 is 421 or 855, Ruby is 415, Sapphire is 416 or 619 and Black Pearl is 417 or 617. Phase-aware marketplaces show the phase in the listing title, and BO5's inspect servers show it in game.
