The choice between painting your ceiling grey or leaving it white for an industrial look and feel ultimately depends on your personal preference and the overall aesthetic you are trying to achieve.
A white ceiling can create a bright, clean, and modern look that can enhance the industrial feel of your space. It also allows you to play with different textures and materials in your decor, such as exposed pipes and ductwork, to create an industrial look.
On the other hand, a grey ceiling can add depth and dimension to your space, and can also complement the industrial materials used in the room, such as concrete and metal. A darker shade of grey can also help create a more intimate and cozy feel in your space.
It's important to consider the natural and artificial light in your space, as well as the other elements in the room, such as the walls, flooring, and furniture, when deciding on the color for your ceiling. Experimenting with different shades of grey and white, or even other colors, may help you find the perfect match for your space.
Ultimately, the best approach is to choose a color that you love and that complements the overall aesthetic of your space, whether it's a white or grey ceiling.
