Gemini OR-38 / FDM-OR-38 is an off-white lustrous powder that is composed of Mica, Titanium Dioxide, and Silica. Gemini Iridescent Pigments produce a distinctive dual-color appearance, creating striking and dramatic effects. All Gemini Pigments are based on TiO2 or Iron Oxide coated Mica with a thin layer of a Silicone Dioxide and Iron Oxide. Light interference from colored highlight, an additional and strong iridescent color is also reflected from the finely controlled layer of silicone dioxide. The interplay between the various highlight colors in Gemini Iridescent Pigments cannot be duplicated by any combination of blended interference pigments.

双子座OR-38 / FDM-OR-38是由云母，二氧化钛和二氧化硅组成的灰白色光泽粉末。双子座彩虹色产生独特的双色外观，创造惊人的和戏剧性的效果。所有双子座颜料均基于二氧化钛或氧化铁涂层的云母，具有二氧化硅和氧化铁的薄层。彩色高光产生的光线干扰，另外还有强烈的彩虹色，也从精细控制的二氧化硅层反射出来。双子座彩虹色各种高光颜色之间的相互作用不能通过混合干涉颜料的任何组合来复制。
