1. Style and atmosphere: Black doors usually give people a slightly cool, upscale and calm feeling. This feeling is suitable for some modern, exquisite or highly designed hotels. If the hotel wants to create a more warm and relaxed atmosphere, then Black Gate may not be the first choice.

2. Harmony between space and color: If the whole hotel room is decorated with dark colors, the black door may be in harmony with other elements. If the whole room is dominated by bright colors, it may make the black door visually abrupt.
