Why should I repeat an accent color three times in bedroom decor?

Repeating an accent color three to five times in bedroom decor creates harmony and balance. This technique, known as the rule of threes, visually ties the room together and guides the eye smoothly. For example, using rust-colored pillows, a throw, and a plant pot anchors the accent color while adding warmth. Repetition avoids feeling random and makes a monochrome or neutral room feel intentional, cozy, and styled without repainting or dramatic changes.
