If you just moved in and you have the opportunity to start anew, working with a blank canvas, the world is your oyster. If, on the other hand, you are working with what you’ve already got, you’ll need to be mindful of other dominant colours in the room. There’s nothing wrong with clashing, and it’s never that interesting when things match to perfection, but you want to avoid anything that will be particularly jarring. E.g. if you already have lots of vibrant colour in your soft furnishings — and perhaps a statement coloured sofa — are you best off keeping your wall prints muted? Try to avoid having everything competing for dominance in the one space. Or, if your room is already pared back as is, you can afford to go bolder with your wall art. Having an accent colour in mind will narrow your search.
