Dual, tri-colour and rainbow reels change colour along the spool or across the nozzle, so larger prints and slower outer walls show the effect best.
PLA Silk Rainbow basics: PLA is the easiest 3D printing filament to run: it prints cool, barely warps, and works on any open-frame printer. As a starting point, print PLA Silk Rainbow at 190–230°C with the bed at 35–60°C; it doesn't need an enclosure. The temperature range printed on the reel always wins: it varies between brands and between colours of the same brand.
Colour names vary between brands, so check the listing photos before buying if you need to match an existing reel. Every card shows the live price and whether it is in stock, and the list is sorted by price per kilogram.
