A huge trend right now is ombre (having colors or tones that shade into each other) and it’s such an easy DIY. If you have a room with an exposed radiator try painting it with several shades of one color for an awesome effect. {Just be careful if there are small children around, I would advise a radiator cover instead.}
Another super easy trick is to purchase an inexpensive unfinished dresser or desk, or reuse an existing piece you already have, and paint each drawer a different shade. The effect is fresh and unique and will match the rest of your decor.
Of course you can also always create the ombre effect with wall paint. I love the idea of a chevron ombre!
