If you want your room to express peace and happiness, pale yellow and periwinkle blue are your colors. These colors give off cheerful vibes in waves. If you’re not sure how to execute these colors in your space, start by grabbing a bucket of soft yellow paint for an accent wall, looking at some pale yellow sheet sets, a white waffle duvet cover, and a fun periwinkle blue lounge chair to make your room pop and pull it all together.
