The method of claim 1, wherein said oxidizing agent is a strong nucleophile. 10. The method of claim 9, wherein said strong nucleophile is an alkoxide. 11. The method of claim 1, wherein said mixture is black. 12. The method of claim 1, wherein said substrate is paper. 13. The method of claim 12, wherein said paper is non-porous paper. 14. The method of claim 1, wherein said eradicable dye is a triarylmethane derivative. 15. The method of claim 1, wherein said eradicable dye is present in said mixture in an amount at least about 0.01% and up to about 40% by weight of the total weight of the mixture. 16. The method of claim 15, wherein said eradicable dye is present in said mixture in an amount at least about 0.1% and up to about 10% by weight of the total weight of the mixture. 17. The method of claim 1, wherein said colored pigment is present in said mixture in an amount at least about 0.01% and up to about 50% by weight of the total weight of the mixture. 18. The method of claim 17, wherein said colored pigment is present in said mixture in an amount at least about 0.1% and up to about 20% by weight of the total weight of the mixture. 19. The method of claim 1, wherein said mixture further comprises a non-eradicable dye. 20. The method of claim 19, wherein said non-eradicable dye is selected from the group consisting of non-eradicable blue dyes, non-eradicable red dyes, non-eradicable violet dyes, non-eradicable yellow dyes, non-eradicable orange dyes, and combinations of the foregoing. 21. The method of claim 1, wherein said applying said mixture comprises dispensing said mixture from a writing instrument. 22. The method of claim 1, wherein said applying said mixture comprises dispensing said mixture from a printer cartridge. 23. The method of claim 22, said applying said mixture comprises dispensing said mixture from a continuous ink-jet printhead. 24. The method of claim 22, said applying said mixture comprises dispensing said mixture from a drop-on-demand ink-jet printhead. 25.
