Claim 11:
12. A system comprising:
a cosmetic sponge;
a thermochromic pigment in at least a portion of the cosmetic sponge, wherein the thermochromic pigment is configured to change the portion of the cosmetic sponge from a first color at a first temperature to a second color at a second temperature in response to absorbing liquid by the cosmetic sponge, wherein the liquid is at least at the second temperature thereby signaling the cosmetic sponge is damp before use;
wherein the cosmetic sponge is configured to apply makeup while the portion of the cosmetic sponge is the second color;
wherein the portion of the cosmetic sponge having the thermochromic pigment is configured to change from the second color to the first color as the cosmetic sponge returns to the first temperature based on passage of a period of time wherein a color transition happening at a period of time before completion of the applying of the makeup serves as a visual indicator to a user that the user needs to dampen the cosmetic sponge.
