What is claimed is: 1. A process for preparing a dyeing composition for dyeing keratinous fibers, comprising percolating steam under a pressure of at least 3 bar through at least one pulverulent compound capable of generating a solution capable of dyeing keratinous fibers. 2. The process according to claim 1, wherein the keratinous fibers are human keratinous fibers. 3. The process according to claim 2, wherein the human keratinous fibers are hair. 4. The process according to claim 1, wherein the at least one pulverulent compound capable of generating a solution capable of dyeing keratinous fibers is chosen from oxidation bases, couplers, and direct dyes. 5. The process according to claim 4, wherein said oxidation bases are chosen from para-phenylenediamines, bisphenylalkylenediamines, para-aminophenols, ortho-aminophenols, heterocyclic bases, and the addition salts thereof. 6. The process according to claim 4, wherein said couplers are chosen from meta-phenylenediamines, meta-aminophenols, meta-diphenols, naphthalene couplers, heterocyclic couplers, and the addition salts thereof. 7. The process according to claim 4, wherein said direct dyes are chosen from nitrobenzene direct dyes, azo direct dyes, quinone direct dyes, azine direct dyes, triarylmethane direct dyes, indoamine direct dyes, natural direct dyes, and methine direct dyes, wherein said direct dyes may be non-ionic, anionic, or cationic. 8. The process according to claim 1, wherein the at least one pulverulent compound capable of generating a solution capable of dyeing keratinous fibers is chosen from compounds obtained from plant or animal species. 9. The process according to claim 8, wherein the compounds obtained from plant species are chosen from hydroxylated quinone, indigoids, hydroxyflavones, santalin A and santalin B, isatin and the derivatives thereof, and brasilin and the hydroxylated derivative thereof. 10. The process according to claim 8, wherein the plant species are chosen from henna, indigo, mayweed, annatto, and alkanet. 11. The process according to claim 8, wherein the animal species are chosen from cochineal insects. 12. The process according to claim 1, wherein the percolation is carried out with steam under a pressure of at least 4 bar. 13. The process according to claim 12, wherein the percolation is carried out with steam under a pressure of at least 10 bar. 14. The process according to claim 13, wherein the percolation is carried out with steam under a pressure ranging from 10 to 30 bar. 15. A process for dyeing keratinous fibers, comprising preparing a dyeing composition, comprising percolating steam under a pressure of at least 3 bar through at least one pulverulent compound capable of generating a solution capable of dyeing keratinous fibers; and applying the dyeing composition to the keratinous fibers for a time sufficient to develop a desired coloration. 16. The process according to claim 15, wherein the keratinous fibers are human keratinous fibers. 17. The process according to claim 16, wherein the human keratinous fibers are hair. 18. The process according to claim 15, wherein the at least one pulverulent compound capable of generating a solution capable of dyeing keratinous fibers is chosen from oxidation bases, couplers, and direct dyes. 19. The process according to claim 15, wherein the at least one pulverulent compound capable of generating a solution capable of dyeing keratinous fibers is chosen from compounds obtained from plant and animal species. 20. A device for packaging at least one pulverulent compound capable of generating a solution capable of dyeing keratinous fibers, comprising a closed housing delimited by at least one wall at least partially permeable to steam under a pressure of at least 3 bar, wherein the closed housing comprises the at least one pulverulent compound capable of generating a solution capable of dyeing keratinous fibers. 21. The device according to claim 20, wherein the closed housing is delimited by two sealed sheets. 22. The device according to claim 20, wherein the closed housing is delimited by a container closed by a lid.
