Whether you need a white shell or a black shell or the multicolor silicone sleeve, the conventional one is white, which is the most widely used, but there are also black shells, which are black when not emitting light. Other colors, such as red, green, blue, yellow, orange, etc., are mostly used in advertising signs, contour lights, etc. The color of the silicone is consistent with the color of the light strip, and it blends better with the environment.
