3 . The pigment of claim 1 , wherein the intermetallic compound is a two-component binary intermetallic compound.

4 . The pigment of claim 1 , wherein the intermetallic compound is a three-component ternary intermetallic compound.

5 . The pigment of claim 1 , wherein the intermetallic compound is a four-component quaternary intermetallic compound.

6 . The pigment of claim 1 , wherein the intermetallic compound is a five-component quinary intermetallic compound. The pigment of claim 1 , further comprising, at least one dielectric layer.

8 . The pigment of claim 1 , further comprising, at least one absorber layer.

9 . A pigment, comprising:
a semi-transparent absorber layer including an intermetallic compound, wherein the intermetallic compound is a crystal structure of at least two different elemental metals chemically bonded together.

10 . The pigment of claim 9 , wherein the intermetallic compound is selected from the group consisting of CoAs 2 , NiSb, Cu 3 As, duraluminum, CuAl 2 , FeCo, FeAl, Fe 2 Al 3 , FeAl 2 , FeAl 3 , Fe 3 Al, Fe 2 Nb, FeNb, ZrNi, Zr 2 Ni, ZrNi, Zr 3 Fe, TiZn, Ti 2 Zn, TiZn 2 , TiAl, Ti 2 Ni, TiNi, TiNi 3 , TiCo, TiCo 2 , TbAl, Tb 2 Al, Ni 3 Al, Cr 3 Pt, Cr 2 Nb, Alnico, sendust, terfenol-D, CoAl, AlGd, AlGd 2 , Ni 80 Ti 5 Nb 15 , TbPtGa, La 2 Co 17-x Ta x in which x is 0.5 and 0.6, HoCo 2 B 2 C, GdNi 2 B 2 C, (Y 1-x Gd x )Ni 2 B 2 C, ErCo 2 B 2 C, and (Y 1-x Gd x )Ni 2 B 2 C.

11 . The pigment of claim 9 , wherein the intermetallic compound is a two-component binary intermetallic compound.

12 . The pigment of claim 9 , further comprising, at least one reflector layer.

13 . The pigment of claim 9 , further comprising, at least one dielectric layer.

14 . A composition comprising the pigment of claim 1 dispersed in a liquid medium.

15 . A composition comprising the pigment of claim 9 dispersed in a liquid medium.

16 . A method of making a pigment, comprising:
depositing, onto a substrate, a layer including an intermetallic compound by thermal evaporation in vacuum or co-evaporation, wherein the intermetallic compound is a crystal structure of at least two different elemental metals chemically bonded together.

17 . The method of claim 16 , further comprising depositing at least one additional layer chosen from a reflector layer, a dielectric layer, and an absorber layer between the substrate and the layer including the intermetallic compound.

18 . The method of claim 16 , further comprising depositing, onto the layer including an intermetallic compound, at least one additional layer chosen from a reflector layer, a dielectric layer, and an absorber layer.

19 . The method of claim 16 , wherein the layer including an intermetallic compound is a semi-transparent absorber layer and has increased durability as compared to an absorber layer that does not include the intermetallic compound.

20 . The method of claim 16 , wherein the layer including an intermetallic compound is a magnetic reflector layer and is corrosion resistant as compared to a reflector layer that does not include the intermetallic compound.
