Dual colorants are disclosed. The colorants of the present invention include at least one compound, which exhibits a first color outside an aqueous environment and a second color after placement into an aqueous environment. In some cases, the colorant includes an oil-soluble dye capable of exhibiting the first color and a water-soluble dye capable of exhibiting the second color. In certain embodiments, such colorants may be used in toilets. In these embodiments, the first color corresponds to a color associated with a fragrance, such as red for rose, while the second color corresponds to a color associated with cleanliness in a toilet, such as blue or green.

I claim: 1. A colorant comprising a plurality of dyes, consisting of: a fragrance, an oil-soluble dye capable of exhibiting a first color when in a non-aqueous environment, said color being indicative of said fragrance, and a water-soluble dye capable of exhibiting a second color when in an aqueous

I claim: 1. A colorant comprising a plurality of dyes, consisting of: a fragrance, an oil-soluble dye capable of exhibiting a first color when in a non-aqueous environment, said color being indicative of said fragrance, and a water-soluble dye capable of exhibiting a second color when in an aqueous environment; wherein the colorant exhibits the first color before introduction to an aqueous environment, and wherein the first color and at least a portion of the aqueous environment exhibit the second color when said colorant has been inserted into an aqueous environment. 2. The colorant of claim 1, further comprising an effervescent comprising an acid and a salt. 3. The colorant of claim 1, wherein the colorant is non-hygroscopic. 4. The colorant of claim 1, wherein the first color is selected from the group consisting of yellow, red, purple, orange and pink and the second color is selected from the group consisting of blue and green. 5. The colorant of claim 1, further comprising a surfactant. 6. The colorant of claim 1, further comprising an absorbing agent. 7. The colorant of claim 1, wherein the colorant is in tablet form. 8. The colorant of claim 1, wherein the aqueous environment is in a toilet bowl. 9. A process for treating water in a toilet bowl comprising: providing a composition comprising a colorant comprising a plurality of dyes, consisting of an oil-soluble dye capable of exhibiting a first color when in a non-aqueous environment, and a water-soluble dye capable of exhibiting a second color when in an aqueous environment; said composition further comprising at least one cleaning compound, wherein the composition exhibits said first color outside an aqueous environment; and placing the composition into an aqueous environment, wherein the first color and at least a portion of the aqueous environment exhibit said second color. 10. The process of claim 9, wherein the composition further comprises an effervescent. 11. The process of claim 10, wherein the effervescent comprises an acid and a salt. 12. The process of claim 9, wherein the colorant comprises an oil-soluble dye and a water-soluble dye that are mixed. 13. The process of claim 9, wherein the first color is selected from the group consisting of yellow, red, purple, orange and pink and the second color is selected from the group consisting of blue and green. 14. The process of claim 9, wherein the composition comprises a fragrance and said first color is indicative of said fragrance. 15. The process of claim 9, wherein the composition comprises a surfactant. 16. The process of claim 9, wherein the composition comprises an absorbing agent. 17. The process of claim 9, further comprising placing the composition in a reagent vessel. 18. The process of claim 9, wherein the composition is in tablet form. 19. A process for making a colored composition useful for cleaning comprising: providing an oil-soluble dye capable of exhibiting a first color in the absence of an aqueous environment; providing a water-soluble dye capable of exhibiting a second color in an aqueous environment; and mixing the oil-soluble dye and the water-soluble dye with a cleaning material and an effervescent material comprising an acid and a salt and pressing the composition into a tablet. 20. The process of claim 19, wherein the first color is selected from the group consisting of yellow, red, purple, orange and pink and the second color is selected from the group consisting of blue and green. 21. The process of claim 19, further comprising providing a fragrance. 22. The process of claim 19, further comprising providing a non-hygroscopic compound. 23. The process of claim 19, further comprising providing an absorbing agent.
