About multicolour filament
Multicolour filament gives you more than one colour from a single spool, with no multi-material unit. Dual and tri-colour filament shows a different colour depending on the side you look from; rainbow and gradient filament changes colour along the spool.
Rainbow and gradient spools change colour every few metres, so a small print may show only one or two colours. Dual and tri-colour filament looks best on prints seen from several sides, such as vases and figures.
