Thebackground layer 202 may be an opaque light-shielding layer. Thebackground layer 202 is similar to thebackground layer 102 shown in fig. 8 and will not be described in detail here.

In another embodiment, thebackground layer 202 is formed between thebasecoat layer 208 and thesubstrate 201, with the color icon A, B, C, D offset from thebackground layer 202. Thebackground layer 202 is formed on thesubstrate 201 to leave a region where the color icon A, B, C, D is required, thebackground layer 208 is formed on thebackground layer 202 and the region left on thesubstrate 201, and the color icon A, B, C, D is formed on thebackground layer 208. The colored icon A, B, C, D does not overlap with thebackground layer 202.

In another embodiment, thebackground layer 202 is formed on thesubstrate 201, and thebase color layer 208 and the colored icons A, B, C, D are offset from thebackground layer 202. The material of thebase color layer 208 may be saved. Thebase color layer 208 and the color icon A, B, C, D are overlapped, and the color icon A, B, C, D is positioned on the side of thebase color layer 208 opposite to thesubstrate 201, so that thebase color layer 208 and the color icon A, B, C, D are not overlapped with thebackground layer 202 for hiding the color icon.

In another embodiment, thesubstrate 201 is a translucent substrate and the hidden color icon is formed on the translucent substrate. Thebase color layer 208 may be omitted, thecolor icon layer 203 may be directly formed on the surface of thesubstrate 201, and thebackground layer 202 may also be directly formed on the surface of thesubstrate 201. The process is simplified.

Similar to thediffusion layer 104 shown in fig. 8, in the embodiment shown in fig. 10, atranslucent diffusion layer 204 may be formed by screen printing on the side of thecolor mark layer 103 facing away from thesubstrate 201, as shown in fig. 4 in fig. 10, and described in detail above.
