What is the 60-30-10 rule in Christmas decor color schemes?

The 60-30-10 rule guides Christmas decor by allocating sixty percent of the space to a dominant color, thirty percent to a secondary color, and ten percent to an accent. For IKEA Christmas 2025, red often takes sixty percent, green thirty, and a modern accent like candy pink fills ten percent. This balance keeps the decor bold yet harmonious, allowing playful motifs and layered lighting to shine without overwhelming the senses.
