We use no dyes or pigments. Instead, laser technology modifies the surface itself, creating a periodic structure on the scale of hundreds of nanometers — dimensions comparable to the wavelength of visible light. It is this structure that determines which colors reach your eye.

The principle is similar as in the wings of the Morpho butterfly. Incoming white light is split by the nanostructure into its spectral components — a rainbow of colors. The colors shift with viewing angle and light source, which is why every moment looks different.

The structure is part of the material itself. Thanks to tungsten — one of the hardest metals on Earth — the effect is permanent and will not wear off like conventional surface coatings.
