The Ultra Travel Series of pigments combines two leading technologies to create unrivalled visual impact. The interference effect is generated by multiple layers of metal oxide on a borosilicate substrate. As the angle of incidence changes, the perceived colour to the eye changes. This creates an eye-catching effect as the object or user moves position. These pigments also contain an inorganic colourant to increase impact. This colourant provides increased obscuration and gives a brighter visual appearance to the pigments.
