Provided are a panel member having good aesthetic properties and good visual recognition of characters, figures, symbols, and the like, and an electronic musical instrument having the panel member. An operation panel has a base layer (341) including a transmission portion (341a) that transmits visible light and is shaped like an identification (I), and a base portion (341b) that surrounds the transmission portion (341a) and has a lower transmittance of visible light than the transmission portion (341a); a first color-developing layer (342) that is positioned at a higher layer than the base layer (341), is formed of a certain color, and transmits at least a portion of visible light; a diffuse reflection layer (343) that is positioned at a higher layer than the first color-developing layer (342) and diffusely reflects at least a portion of visible light; and a second color-developing layer (344) that is positioned at a higher layer than the diffuse reflection layer (343) or inside the diffuse reflection layer (343) and is formed inside the shape of the identification (I) of the transmission portion (341a) when viewed from above.

The application provides a coating weather resistance verification method, a coating system and an automobile body part, and the method comprises the following steps: determining a corresponding coating system according to a selected coated substrate; using the coating system to adjust target automobile body colors according to the weather resistance requirements of different parts, and forming differentiated coating formulas; performing comprehensive performance tests on at least one target automobile body color, and obtaining the target color paste type used by the target automobile body color when the test is passed; obtaining the ratio of pigments to binders of the color paint layer in the test passed coating formula, and taking the maximum value in the ratio as the limit color base ratio; combining the coating of the coating system with the target color paste type, and adjusting according to the limit color base ratio, and performing weather resistance verification on the adjusted test coating. In this way, the weather resistance of the coating can be tested while ensuring that the stone impact resistance, scratch resistance, chemical resistance and other performances of the coating are not affected, the development cycle of the coating is greatly shortened, and the development efficiency is improved.
