The 70 20 10 rule in interior design is a simple yet effective guideline for creating visually appealing spaces. It suggests using 70% of a dominant color, 20% of a secondary color, and 10% of an accent color. This approach helps in achieving a balanced and cohesive look in any room.
What is the 70 20 10 Rule in Interior Design?
The 70 20 10 rule is a classic interior design principle that helps in color distribution within a space. This rule ensures that a room feels harmonious and well-balanced by strategically using colors. Here’s how it works:
- 70% Dominant Color: This forms the base of the room, usually applied to walls, large furnishings, and flooring.
- 20% Secondary Color: This supports the dominant color and is typically used for upholstery, rugs, or curtains.
- 10% Accent Color: This adds interest and contrast, often found in pillows, artwork, or decorative accessories.
Why Use the 70 20 10 Rule?
Balance and Harmony: By following this rule, you can create a room that feels balanced. The dominant color sets a stable foundation, while the secondary and accent colors add depth and interest.
Ease of Application: This rule simplifies the color selection process, making it easier for both novice and experienced designers to achieve a cohesive look.
Flexibility: It allows for creativity within a structured framework, enabling you to play with various color combinations while maintaining a unified appearance.

Living Room
In a living room, you might use a neutral color like beige as the dominant shade for walls and large pieces of furniture. A secondary color, such as navy blue, could be incorporated through an area rug and curtains. Finally, a bold accent color like mustard yellow could be introduced via throw pillows and artwork.

For a bedroom, consider using a calming color like soft gray as the dominant hue. A secondary color, such as lavender, could be used for bedding and drapes. An accent color like teal might be introduced through lamps and decorative accessories.
