When choosing ambient lighting, consider the room size, ceiling height, and the mood you want to create. Overhead fixtures like chandeliers or pendant lights can provide general ambient lighting. Ensure the fixture's size is proportionate to the room, and the light is diffused to avoid harsh shadows.
As well as this, indirect lighting, such as floor lamps, can also contribute to ambient lighting without being the sole light source. Experiment with different fixtures and their placement to achieve a balanced and pleasing ambient light in your space.
