摘要:
A method of providing a configuration of a system of interference filters with a visible color shifting effect, includes: a hue matching step of identifying a configuration of a first interference filter including two first metal layers and a first spacer layer therebetween, and a configuration of a second interference filter including two second metal layers and a second spacer layer therebetween, wherein the first and second filters match in hue at the first viewing angle, and the mismatch in hue at the second angle; and a lightness adjustment step which may include modifying the layer material or the layer thickness of one of the metal layers; wherein a difference in lightness at the first viewing angle between the first and second modified filters is less that a difference in lightness at the first viewing angle between the first and second filters.
