Bright colors - harmony or contrast?
When you decorate your home with art, it lifts the whole interior and the entire room to another level. Imagine this hall without any art works on the walls.. -it would just be a plain white room. Delicate perhaps, but still quite boring.
If your walls are bright like these, you could either hang up light and bright colored art and you will create a great harmony between the art and the interior. Or you can chose darker colors in the art and get great contrasts. There is also a possibility to use a dark frame as the one on the left side to create a contrast even if the painting is painted in bright colors.
