mixing the fungal pigment/organic solvent solution or suspension with an oil carrier; and evaporating the organic solvent resulting in a composition comprising the fungal pigment suspended or solvated in the oil carrier, wherein the fungal pigment is an extracellular pigment from a fungi selected from the Chlorociboria genus, the Scytalidium genus, or any mixture thereof, and wherein the composition does not include an organic solvent. ### Claim 22 (depends on 21) The method of claim 21, wherein the oil carrier is a plant oil, mineral oil or animal oil. ### Claim 23 (depends on 21) The method of claim 21, wherein the oil carrier is raw linseed oil. ### Claim 24 (depends on 21) The method of claim 21, wherein the fungal pigment is from a fungi selected from C. aeruginascens, C. aeruginosa, S. cuboideum, S. lignicola, S. ganodermophthorum, or a mixture thereof. ### Claim 25 (depends on 21) The method of claim 21, wherein preparing a fungal pigment/organic solvent solution or suspension comprises extracting the fungal pigment from wood with the organic solvent. ### Claim 26 (depends on 25) The method of claim 25, wherein the organic solvent is selected from dichloromethane, chloroform, pyridine, acetone, tetrahydrofuran, or acetonitrile. ### Claim 27 (depends on 25) The method of claim 25, wherein the organic solvent is selected from dichloromethane, chloroform, or pyridine. ### Claim 28 A method for making a composition comprising: preparing a fungal pigment/organic solvent solution or suspension; mixing the fungal pigment/organic solvent solution or suspension with a water carrier; and removing the organic solvent resulting in a composition comprising the fungal pigment suspended or solvated in the water carrier, wherein the fungal pigment is an extracellular pigment from a fungi selected from the Chlorociboria genus, the Scytalidium genus, or any mixture thereof, and wherein the composition does not include an organic solvent.
