The filament transitions smoothly through a full rainbow gradient as it unwinds — so every print you make is automatically multicolor without a multi-material system, color swaps, or any extra setup.

The sky doesn't jump from orange to purple instantly — it transitions gradually through every shade in between. That's exactly what this filament does.
