White is the best color for a small space. It enhances the space and it does not look small. You can even use lighter shade colors that will fit your furniture’s theme.
There is no need for any kind of creativity in the layout of the room. The room should be arranged as simple as possible with a minimum number of furniture and just the number of light fixtures that are necessary.
It is always said that dark colors make the room look smaller but actually a dark-colored accent wall can also bring depth to the room and it actually works really well. So, you can definitely try a dark color if you like bright colors.
