Abstract: A dial, and timepiece including the dial, including a mother-of-pearl wafer partially covering a support member, and a decorative element arranged on a reverse of the wafer, the decorative element being visible on an obverse of the wafer when subjected to a stimulus and invisible on the obverse of the wafer in the absence of the stimulus. The decorative element has a first empty area on a reverse of the wafer, and a second empty area on the obverse of the wafer, facing the first empty area. A colour compensation layer is deposited on the first empty area or the second empty area, the colour being selected such that the difference in colour ΔE in the CIE Lab colour space between the colour compensation layer and the decorative element in the absence of said stimulus, perceived by a user observing the obverse of the wafer, is less than 3.

Abstract: A horological component including a substrate and at least one first decoration component including at least one first photoluminescent material configured to procure a phosphorescent appearance. The horological component includes a second decoration component including at least one second material, the second material being metallic and configured to procure a metallic appearance, or variochromic and configured to procure a color that varies under the effect of a stimulus, the first decoration component and the second decoration component being arranged relative to one another on the substrate to form a decoration having a metallic appearance or a color that varies under the effect of a stimulus when the horological component is exposed to light and a phosphorescent appearance when the horological component is in the dark. A timepiece can include such a horological component.
