A color-change laminate in which a color tone derived from a porous layer is visually perceived in a dry state and a metallic lustrous property is visually perceived in a liquid-absorbed state of the porous layer caused by water application is excellent in luminance and which satisfies both of changing properties and decorative properties in the dry state and in the liquid-absorbed state. A color-change laminate includes a support having a metallic lustrous property and a porous layer provided on the surface of the support. The porous layer includes a low-refractive-index pigment and a transparent metallic lustrous pigment formed by coating a transparent core material with a metal oxide and/or a transparent metallic lustrous pigment having a color-flopping property all fixed onto a binder resin in a dispersed state and is different in transparency in a liquid-absorbed state and in a liquid-unabsorbed state.
