Abstract: A composition including a first color shifting pigment having a first color shift that extends from a starting color at normal through a plurality of colors as a viewing angle is increased to a final color, wherein the first color shift rotates counterclockwise relative to, and about, an origin of the L*a*b* color space; and a color filter that transmits a portion of the first color shift of the first color shifting pigment and absorbs a remainder of the first color shift of the first color shifting pigment; wherein the composition has a second color shift different from the first color shift; and wherein the second color shift has a first portion that rotates counterclockwise relative to the origin and a second portion that rotates clockwise relative to the origin is disclosed. A security device including the composition is included. A method of making the composition and a method of authenticating the security device are also disclosed.
