Piano black theme
All doors and windows have been replaced, with the theme of piano black, which is solemn and elegant. If it seems too monotonous or dull, you can put evergreen plants on the balcony. If there is enough space between the balcony and the stairs, you can also make a small flower bed, but the plants should not be tall. The whole frame was replaced by white marble.
Baiyuse theme
All doors and windows are replaced with white jade as a whole, and the doors and windows are highlighted with gray darker than the current frame. Glass must be transparent and cool, preferably ultra-white glass without any color. In this case, a low pine bonsai should be placed on the balcony, tall and straight, evergreen, but not eye-catching. The trees in the yard here can also be replaced with wintersweet or osmanthus.
Yellow theme
You can also change the theme to yellow, the doors and windows are rose red, glass and so on. Try to make them cool. You can match them with red, such as blue and red, which is lavender, but the color should look blue and red, so the stair handrails here can be dark red.
