The pigmented cosmetic composition can comprise a particular set of L*C*h* values such that when deposited onto tonal imperfections, it can result in natural, flawless looking skin, while still remaining substantially undetectable to the naked eye. ## Claims ### Claim 1 A method of camouflaging a tonal imperfection comprising the steps of a. identifying a skin tone of a user having a tonal imperfection using the Skin Tone Identification Method; b. instructing the user to select a pigmented cosmetic composition adapted to camouflage the tonal imperfection based on the user's skin tone; c. selecting the pigmented cosmetic composition; and d. selectively targeting and depositing the selected pigmented cosmetic composition substantially only onto the tonal imperfection; wherein the pigmented cosmetic composition comprises an average composition L* value of about 10 to about 40 units greater than an average skin L* value of the user and an average composition C* value of greater or equal to an average skin C* value of the user. ### Claim 2 (depends on 1) The method of claim 1 wherein the pigmented cosmetic composition comprises an average composition L* value of about 15 to about 35 units greater than an average skin L* value of the user. ### Claim 3 (depends on 1) The method of claim 1 wherein when the average skin L* value of the user is greater than about 55, the average delta C* value between the pigmented cosmetic composition and the user's skin is about 0 to about 13. ### Claim 4 (depends on 1) The method of claim 1 wherein when the average skin L* value of the user is less than or equal to about 55, the average delta C* between the pigmented cosmetic composition and the user's skin is about 14 to about 22. ### Claim 5 (depends on 1) The method of claim 1 wherein the pigmented cosmetic composition comprises an opacity of at least 0.2. ### Claim 6 (depends on 1) The method of claim 1 wherein the pigmented cosmetic composition is deposited onto less than about 10% of the surface area of the user's skin. ### Claim 7 (depends on 1) The method of claim 1 wherein pigmented cosmetic composition is deposited via inkjet deposition, direct contact, and combinations thereof. ### Claim 8 (depends on 1) The method of claim 1 wherein the pigmented cosmetic composition is deposited onto the tonal imperfection in a discontinuous deposition pattern of discrete droplets between about 0.1 μm to about 60 μm in size. ### Claim 9 (depends on 1) The method of claim 1 wherein the pigmented cosmetic composition comprises a metal oxide, wherein the metal oxide comprises an average particle size of greater than 100 nm. ### Claim 10 A method of camouflaging a tonal imperfection comprising the steps of a. providing a pigmented cosmetic composition based on an identified skin tone; and b. selectively targeting and depositing the pigmented cosmetic composition substantially only onto the tonal imperfection; wherein the pigmented cosmetic composition comprises an average composition L* value of about 10 to about 40 units greater than an average skin L* value of the skin tone and an average composition C* value, wherein when the identified skin tone comprises an average L* value of greater than 55, the average delta C* between the pigmented cosmetic composition and the identified skin tone is about 0 to about 13 and when the user's skin has an average skin L* value of less than or equal to about 55, the average delta C* between the pigmented cosmetic composition and identified skin tone is about 14 to about 22. ### Claim 11 (depends on 10) The method of claim 10 wherein the pigmented cosmetic composition comprises an average composition h* value of about 70 to about 80. ### Claim 12 (depends on 10) The method of claim 10 wherein the pigmented cosmetic composition comprises an average composition C* value, wherein when the identified skin tone comprises an average L* value of greater than 55, the average delta C* between the pigmented cosmetic composition and the identified skin tone is about 0 to about 10. ### Claim 13 A method for camouflaging a tonal imperfection comprising the steps of a. providing a guide to a user that allows the user to select a pigmented cosmetic composition adapted to camouflage a tonal imperfection, wherein the pigmented cosmetic composition is available in different shades and the guide recommends a specific shade comprising: i. an average L* value of about 10 to about 40 units greater than an average skin L* value of the user; and ii. an average composition C* value of greater than or equal to an average skin C* value of the user; b. selecting the pigmented cosmetic composition; and c. selectively targeting and depositing the selected pigmented cosmetic composition onto the tonal imperfection with a deposition device. ### Claim 14 (depends on 13) The method of claim 13 wherein when the user's skin comprises an average L* value of greater than 55, the average delta C* between the pigmented cosmetic composition and the user's skin is about 0 to about 13. ### Claim 15 (depends on 13) The method of claim 13 wherein when the user's skin has an average skin L* value of less than or equal to about 55, the average delta C* between the pigmented cosmetic composition and the user's skin is about 14 to about 22. ### Claim 16 A method of camouflaging a tonal imperfection comprising the steps of a. identifying a skin tone of a user having a tonal imperfection using the Skin Tone Identification Method;

wherein the pigmented cosmetic composition comprises an average composition L* value of about 10 to about 40 units greater than an average skin L* value of the user and is deposited onto less than about 10% of the surface area of the user's skin. ### Claim 17 A method of camouflaging a tonal imperfection comprising the steps of a. identifying a skin tone of a user having a tonal imperfection using the Skin Tone Identification Method; b. instructing the user to select a pigmented cosmetic composition adapted to camouflage the tonal imperfection based on the user's skin tone; c. selecting the pigmented cosmetic composition; and d. selectively targeting and depositing the selected pigmented cosmetic composition substantially only onto the tonal imperfection; wherein the pigmented cosmetic composition comprises an average composition L* value of about 10 to about 40 units greater than an average skin L* value of the user and is deposited onto the tonal imperfection in a discontinuous deposition pattern of discrete droplets between about 0.1 μm to about 60 μm in size. ### Claim 18 A method of camouflaging a tonal imperfection comprising the steps of a. identifying a skin tone of a user having a tonal imperfection using the Skin Tone Identification Method; b. instructing the user to select a pigmented cosmetic composition adapted to camouflage the tonal imperfection based on the user's skin tone; c. selecting the pigmented cosmetic composition; and d. selectively targeting and depositing the selected pigmented cosmetic composition substantially only onto the tonal imperfection; wherein the pigmented cosmetic composition comprises an average composition L* value of about 10 to about 40 units greater than an average skin L* value of the user and the pigmented cosmetic composition comprises a metal oxide, wherein the metal oxide comprises an average particle size of greater than 100 nm.
