The matching of the door handle and the door is generally based on the style of the door to determine the style of the door handle. Here are some collocation suggestions I give:
①White door + black door handle
Black and white match, this is a very elegant and fashionable design, if the door is white, then the black door handle is the best match!

②Dark wood color door + golden door handle
Darker colored doors are generally used in thicker styles such as Chinese and American styles, which are usually more harmonious and beautiful with golden handles.
③Light wood color door + black door handle
The light wood color is a relatively simple door, and if it is matched with a black door handle, the overall effect is more modern and generous.
④Light wood color door + golden door handle
If it is a light luxury space, light wood-colored door, with golden door handle, the effect is also more gorgeous and delicate.
The above are the matching suggestions based on the color of the door. The reason why silver is not mentioned is that silver is often more rustic. Unless there are a lot of silver design elements in the space, it is not recommended to use silver door handles. However, if the overall decoration style is considered comprehensively, for example, in some light luxury styles with more metal elements, the golden door handle is a detail design that increases the sense of light luxury in the space.
