First off, what kind of work do you do? Do you need a super organised desk, multiple screens, or lots of room to spread out? And how do you want to feel whilst you're in that space: focused, calm, creative, or energised? Think about balancing energies. If your work is fast-paced, why not consider soothing, calming colours? Alternatively, if you struggle to make it through the afternoon, opt for energising palettes. If your job requires creativity, you could go one of two ways: neutrals for a blank canvas or bright colours to get your creative juices flowing. It's your space, after all, so choose colours that reflect your personality.
Unless, of course, it isn't. If you're sharing an office space with someone, there are ways to harmonise your styles. What about jumping on the 'new neutrals' trend and adding a splash of colour to your space without it being overwhelming? And don't forget the golden decorating rule: lighting. What time is it where (you don't want the sun in your eyes for every 9 am Zoom catchup), and when are you using the space.
