Why is the 70 20 10 Rule Important in Decorating?

The 70 20 10 rule is a fundamental principle in interior design that helps create visually appealing and balanced spaces. This rule suggests dividing a room’s color scheme into three parts: 70% of a dominant color, 20% of a secondary color, and 10% of an accent color. By adhering to this rule, decorators can achieve harmony and interest in their designs.

What is the 70 20 10 Rule in Decorating?

The 70 20 10 rule is a guideline used by interior designers to ensure a cohesive and balanced color scheme within a space. Here’s how it works:

  • 70% Dominant Color: This is the main color of the room and is typically used on walls, large pieces of furniture, or flooring. It sets the tone for the space and provides a backdrop for other colors.

  • 20% Secondary Color: This color supports the dominant color and is often used for upholstery, rugs, or curtains. It adds depth and contrast to the room without overpowering it.

  • 10% Accent Color: This is the pop of color that adds interest and personality to the space. It can be introduced through accessories like cushions, artwork, or decorative items.

Creating Balance and Harmony

The 70 20 10 rule maintains a balanced look by ensuring that no single color overwhelms the space. By following this ratio, the dominant color provides a sense of cohesion, while the secondary and accent colors add layers and complexity.

Adding Visual Interest

Using a 10% accent color introduces a focal point that draws attention and adds excitement. This approach prevents the room from feeling monotonous and encourages visual exploration.

Simplifying Design Choices

For those new to decorating, the 70 20 10 rule simplifies decision-making by providing a clear framework. It reduces the risk of overcomplicating color schemes and ensures a professional finish.

  • 10% Accent Color: Yellow throw pillows and a few decorative vases add a vibrant touch.

Bedroom Example

  • 70% Dominant Color: White walls and bedding provide a clean, serene foundation.
  • 20% Secondary Color: Light wood furniture and beige curtains add warmth and texture.
  • 10% Accent Color: Green plants and artwork bring in a refreshing burst of color.

How to Implement the 70 20 10 Rule

Step-by-Step Guide

  1. Choose Your Dominant Color: Select a color that sets the mood for the room. Neutral tones are often used for versatility.

  2. Select a Secondary Color: Pick a color that complements the dominant color and adds depth. This can be a slightly darker or lighter shade.

  3. Add an Accent Color: Introduce a bold color that contrasts with the other two. This color should be used sparingly but effectively.

Tips for Success
