Abstract
A security article may include a substrate. The security article may include a layer of security ink. The layer of security ink may include a set of color-shifting interference particles. The security article may include a layer of magnetic color-shifting ink. The layer of magnetic color-shifting ink may include a set of magnetically aligned magnetic particles. A color-shifting property of the layer of security ink and a color-shifting property of the layer of magnetic color-shifting ink may have a threshold level of similarity to create a color matching effect.
