Color/Blue
< Color
Blue pyramids were released in 1999, one of the first colors of die-injected plastic pyramids ever to be produced. They were first sold in a clear acrylic box of the game Icehouse: the Martian Chess Set, which contained 15 blue pyramids along with equal amounts of red, yellow, and green. They are given the designation "Rainbow" in the Rainbow vs Xeno classification. Blue pyramids are a transparent color, and are not to be confused with another transparent color, Cyan, a pyramid color in a lighter shade of blue introduced four years after the original blue. Blue is the only transparent pyramid color to have a transparent cousin of the same common name (i.e. both are commonly referred to as "blue" in the Western world).
