Colors included
Based on this tube's colors, these builds and videos should be possible.
These builds use your tube colors as substitutes when the original colors are missing.
Rainbow Mix is the classic bold spectrum set — the tube you reach for when you want every color of the rainbow within arm's reach.
With 240 pieces spread across 7 colors, it supports flags, pride-inspired art, patterned frames, and cheerful abstract builds.
Expect a lively blend of Red, Yellow, Purple, Orange, White, Turquoise, Apple, balanced so single-color areas and multicolor stripes both feel natural.
It is one of the most flexible open-play tubes for classrooms, siblings sharing one set, and builders who change ideas often.
Rainbow Mix encourages pure imagination: no required model, just a full color toolkit in a portable Plus-Plus tube.
Suggested for ages 5+
