Specialising in innovative surface treatments, Positive Coating unveils an exclusive version of MorphoColor: dichroic colours with a chameleon effect that change according to the surface finish, the angle of observation and the light, creatings a unique aesthetic dimension.
You have probably already noticed the bright, dancing colour gradients that can sometimes be seen on simple soap bubbles. These are caused by a phenomenon of interference linked to the wave-based nature of light. Using ALD (Atomic Layer Deposition) technology, the company applies this same principle, which now makes it possible to offer a wide range of coloured coatings while controlling the thickness of the layers applied.
Whether machined with a milling cutter or by laser, the surface finish of the piece to be coated (polished, brushed, beadblasted, etc.) or adorned with a design created by engraving, chasing, guilloché work, Côtes de Genève, circular graining or sunburst finishing, will radiate a different kind of vibrancy. The surface finish of the components to be coated interacts with the perception of colour and therefore adds an extra ingredient: depth, sparkle, shine, reflection, intensity, mattness and softness.
MorphoColor is available in three variations: amber raspberry, celestial green and turquoise purple. The company has exploited the interference characteristics of ALD colours to create these decorative coatings, which offer spectacular variations that change with the observer’s every move.
Although chameleon-effect colours have already been presented, particularly in the automotive industry, this effect is simulated by pigments. MorphoColor, on the other hand, is based on a natural optical phenomenon involving light interference. Like a chameleon, which adjusts the arrangement of its nanocrystals to change the way light is reflected, MorphoColor exploits the characteristics of interference colours to produce a constantly changing play of hues.
