The optic comprises a substrate which has two optics (23,24) carried by one surface (18). They are spaced apart to permit viewing at the same time by a human eye. An optically variable pigment (21) is disposed in the first optic, and a second pigment (22) is disposed in the second optical. The optics have the same colour at one angle of incidence and different colours at all other angles of incidence.
