         1 . A method for making a black cement, concrete, stucco or plaster structure, comprising adding a pyrolized polymer derived ceramic black pigment to a cement, concrete, stucco or plaster material, mixing the combined pigment and material to provide a uniform distribution of the pigment within the material, forming the material into a shape, hardening the material into a black cement, concrete, stucco or plaster structure, whereby the hardened structure has a uniform black color throughout the entirety of a structure. 
     
     
         2 . The method of  claim 1 , wherein the pigment comprises at least about 2% of the structure.

         5 . The method of  claim 1 , wherein the pigment comprises at least about 10% of the structure. 
     
     
         6 . The method of  claim 1 , wherein the pigment comprises at least about 12% of the structure. 
     
     
         7 . The method of  claim 1 , wherein the pigment comprises about 3% to about 8% of the structure. 
     
     
         8 . The method of  claim 1 , wherein the pigment is added to a dry material. 
     
     
         9 . The method of  claim 1 , wherein the pigment is added to a wet material. 
     
     
         10 . The method of  claim 1 , wherein the pigment is added to a liquid material. 
     
     
         11 . The method of  claim 1 , wherein the pigment has a particle size D 50  of less than about 4 μm. 
     
     
         12 . The method of  claim 1 , wherein the pigment has a particle size D 50  of from about 3 μm to about 0.1 μm. 
     
     
         13 . The method of  claim 1 , wherein the pigment has a particle size D 50  of from about 2 μm to about 0.5 μm. 
     
     
         14 . The method of  claim 1 , wherein the structure defines a blackness selected from the group consisting of: PMS 433, Black 3, Black 3, Black 4, Black 5, Black 6, Black 7, Black 2 2×, Black 3 2×, Black 4 2×, Black 5 2×, Black 6 2×, and Black 7 2×. 
     
     
         15 . The method of  claim 1 , wherein the structure defines a uniform blackness throughout the structure, selected from the group consisting of: PMS 433, Black 3, Black 3, Black 4, Black 5, Black 6, Black 7, Black 2 2×, Black 3 2×, Black 4 2×, Black 5 2×, Black 6 2×, and Black 7 2×. 
     
     
         16 . The method of  claim 1 , wherein the structure defines a blackness selected from the group consisting of: Tri-stimulus Colorimeter of X from about 0.05 to about 3.0, Y from about 0.05 to about 3.0, and Z from about 0.05 to about 3.0; a CIE L a b of L of less than about 40; a CIE L a b of L of less about 20; a CIE L a b of L of less than 50, b of less than 1.0 and a of less than 2; and a jetness value of at least about 200 M y . 
     
     
         17 . The method of  claim 1 , wherein the structure defines a uniform blackness throughout the structure, selected from the group consisting of: Tri-stimulus Colorimeter of X from about 0.05 to about 3.0, Y from about 0.05 to about 3.0, and Z from about 0.05 to about 3.0; a CIE L a b of L of less than about 40; a CIE L a b of L of less about 20; a CIE L a b of L of less than 50, b of less than 1.0 and a of less than 2; and a jetness value of at least about 200 M y .
