Lofts can be hard to negotiate with: with no walls creating definite areas, it becomes a bit harder to make the space seem cohesive yet multi-functional. One easy solution is to stick with neutrals and then use one bright accent color to tie the room together, utilizing even the littlest details.
One reason we like this solution so much is that it can be cost effective. Instead of relying on big statement pieces that will cost a pretty penny (i.e. sofas), you can simply use small items like office accessories, lamp shades, throw pillows, etc to connect the designated areas together visually.
