A pigment, comprising:
- a core particle;
- an absorber layer on a portion of a surface of an external layer of a vapor deposited colorant, wherein the absorber layer includes a material chosen from a metal, combinations of metals, and alloys of metals;
- and
- the external layer of the vapor deposited colorant at least partially encapsulates the core particle and the absorber layer, wherein the vapor deposited colorant is a composite layer comprising an organic colored material and an inorganic material,
- wherein the inorganic material is a material having a refractive index ranging from about 1.3 to about 2.3.
A method of making particles, comprising depositing a composite layer of a colorant comprising an organic colored material and an inorganic material on an absorber layer via vapor deposition, wherein the inorganic material is a material having a refractive index ranging from about 1.3 to about 2.3.
