// coloured
ColorParticleOption red = ColorParticleOption.create(FoundationParticles.DYE_SPLASH.get(), FastColor.ARGB32.opaque(0xB02E26));

Want a new generic particle? Add it to FoundationParticles, register its provider in FoundationClient and in FoundationClientNeoForge, and put the JSON + textures under assets/foundation/.

Drifting leaves and fluff

DriftingParticle is for particles you bring yourself (own type + textures) that should float out of a block: leaves from hedges or baskets, wool fluff from sheep.

// Architectury
ParticleProviderRegistry.register(MyParticles.HEDGE_LEAF, sprites -> new DriftingParticle.Provider(sprites, DriftingParticle.Style.LEAF, DriftingParticle.MotionProfile.LEAF, MyConfig::leafParticles));
// NeoForge
event.registerSpriteSet(MyParticles.HEDGE_LEAF.get(), sprites -> new DriftingParticle.Provider(sprites, DriftingParticle.Style.LEAF, DriftingParticle.MotionProfile.LEAF));

Style	Looks like
LEAF	tinted with the biome foliage color, spins, stops on the ground
FLUFF	whitish, rocks gently, slides a bit on the ground, translucent

Profiles: MotionProfile.LEAF, LEAF_RISING (tossed higher), FLUFF – or build your own. The optional BooleanSupplier is checked per spawn, handy for a config toggle.
