INTERFERENCE COLORS
You will surely have observed those lively, dancing color gradients sometimes found on soap bubbles, for example.
These are due to an interference phenomenon, due to the wave nature of light. With ALD technology, POSITIVE COATING uses this principle, and that is what enables us to offer our customers this wide range of colored coatings.
Interference colors depend on the thickness of the layers applied: they follow a color gradient sequence (yellow, orange, magenta, violet, blue, cyan, green, …).
