One spool, the whole spectrum. Long transitions, zero tangles.
$14.99 / spool on Amazon US
Crystal Rainbow is one colorway that behaves like a whole palette. The strand moves through red, orange, yellow, green, blue, and violet in long, slow transitions on a translucent Crystal base, so light passes through the print and the colors glow instead of sitting flat.
A rainbow spool only works if it unwinds perfectly for the whole kilogram; a tangle at hour 30 ruins the story. That is why this line leans on tangle-free mechanical winding, checked spool by spool. Load it, start something tall, and let the material decide the color scheme.

USE-CASE GUIDANCE
Transitions are long by design, so a small trinket may live inside a single hue. Vases, towers, and spiral prints move through several colors in one job. On this spool, scale is the setting that matters most.
See PLA SilkThe Crystal base is translucent. Print thin walls, two or three perimeters, and put a light behind or inside the piece: lamps, window ornaments, and luminaries are where this material earns its name.
See PLAWhere the rainbow starts depends on where the spool sits when you press print. Treat it as a collaborator, not a color picker. If one part must be one exact hue, print that part from the 22-color PLA wall instead.

FAQ
Slowly, on purpose. Expect one to three hues on a mid-size print and the full cycle across large pieces. Small prints may sit inside a single color.
Only by unwinding to the hue you want, since the start point depends on where the spool sits. Honest answer: treat the starting color as a surprise.
Yes. The base is the same Crystal you will find on our PLA wall, so thin walls pass light. Thick, solid prints read more opaque.
