Color/Cyan
Cyan pyramids were first introduced in 2003, contained in the boxed set of IceTowers. They are given the designation "Xeno" in the Rainbow vs Xeno classification. Cyan pyramids are a transparent color, and are not to be confused with another transparent color, Blue, a pyramid color in a darker shade of blue introduced four years before Cyan. Cyan's lighter color makes it more convenient for players to include purple pyramids in games, as it is easier to visually distinguish between cyan and purple at lower light levels compared with the darker blue vs purple. This may be why the new Color die released with Pyramid Arcade includes cyan rather than the dark blue color that was featured on the original Color die. Both Cyan and Blue were included in Pyramid Arcade.
