1. A method comprising:
absorbing liquid with a cosmetic sponge;
changing, via a thermochromic pigment in at least a portion of the cosmetic sponge, the portion of the cosmetic sponge from a first color at a first temperature to a second color at a second temperature, wherein the liquid is at least at the second temperature thereby signaling the cosmetic sponge is damp;
applying makeup with the cosmetic sponge while the portion of the cosmetic sponge is the second color; and
changing, via the thermochromic pigment, the portion of the cosmetic sponge 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.
