What’s the difference between Gamma Doppler phases?

I'm still trying to wrap my head around how the Doppler phases work. I know Phase 1–4 are standard, then there’s Emerald, but what’s the actual visual difference? I’ve seen side-by-side pictures online, but they vary depending on lighting or game settings. I want to pick one that really pops in matches, not just on the market preview screen.

Also, do the phases affect the price much or is it mostly cosmetic? Trying to make a smart choice that I’ll enjoy but also holds some value.

If you're torn between Doppler phases and want something that really pops in-game, I’d recommend the https://dmarket.com/csgo-skins/product-card/butterfly-knife-gamma-doppler. I had the same confusion with lighting and previews, but after testing different skins, this one stood out the most during actual matches. The rich green and black contrast looks amazing mid-game—far better than it does on the market screen. It’s sleek, dynamic, and draws attention every time you flip it.
