Light-transmissible keycap and manufacturing method thereof

A light-transmissible keycap having a first light-transmissible symbol area and a second light-transmissible symbol area, comprising:

• a light-transmissible keycap body, the light-transmissible keycap body having a first predetermined area and a second predetermined area, the first predetermined area enclosing the first light-transmissible symbol area, the second predetermined area enclosing the second light-transmissible symbol area;
• a first light-transmissible color layer disposed on the light-transmissible keycap body, the first light-transmissible color layer covering at least the first predetermined area but not covering the second predetermined area, the first light-transmissible color layer having a first color;
• a first dark color layer disposed on the first light-transmissible color layer, the first dark color layer covering at least first predetermined area but not covering the second predetermined area, the first dark color layer having a first hollow pattern corresponding to the first light-transmissible symbol area;
• a second light-transmissible color layer covering the first dark color layer and the second predetermined area, the second light-transmissible color layer having a second color, the first color being different from the second color, the second light-transmissible color layer having a second hollow pattern corresponding to the first light-transmissible symbol area and communicating with the first hollow pattern;
• and
• a second dark color layer covering the second light-transmissible color layer, the second dark color layer having a third hollow pattern corresponding to the first light-transmissible symbol area and communicating with the second hollow pattern, so as to expose an outer surface of the first light-transmissible color layer through the first hollow pattern, the second hollow pattern, and the third hollow pattern, and the second dark color layer having a fourth hollow pattern corresponding to the second light-transmissible symbol area, so as to expose an outer surface of the second light-transmissible color layer through the fourth hollow pattern;
• wherein when an external light passes through the light-transmissible keycap, the first light-transmissible symbol area emits a light with the first color, and the second light-transmissible symbol area emits a light with the second color.
