What is the 3 colour rule in interior design?

The 3-colour rule (also known as the 60-30-10 rule) is a classic interior styling trick that keeps your space feeling balanced. Split your room’s palette into three proportions so everything works together instead of competing for attention. Here’s how it breaks down: 60% – Your main colour: The foundation of the room. Think walls, large rugs, or your biggest furniture pieces. This sets the overall mood. 30% – Your secondary colour: The supporting act. Upholstery, curtains, or an accent wall. 10% – Your accent colour: Pillows, artwork, lamps, or small décor pieces that bring contrast and a little personality pop. Follow this formula, and your room will feel intentional, cohesive, and effortlessly put together.

Green Sofas, Lounges and Couches

Green sofas bring natural, organic style to any living room, whether you’re going for a full green lounge or just a pop of colour. If your space leans cosy, 2-seaters keep things intimate and inviting, while a bouclé sofa, with its textured, nubby charm, adds depth and character you can actually feel. Want to dial it up a little? Bring in a green armchair and style it alongside your sofa for a bolder, beautifully put-together look.

Style your green colour sofa with coordinating cushions and soft neutrals like white, beige, or tan to create a cohesive, welcoming space. Add hints of green in rugs, curtains, or wall art to tie the room together and let your sofa truly steal the show.

Green sofas are having a moment and it’s easy to see why. They bring that calming, nature-inspired feel indoors while still making a confident style statement. Shades like deep forest or olive feel rich and grounded, offering a fresh alternative to safe neutrals. The result? A sofa that’s versatile, timeless, and cozy with just the right touch of luxury.

Start with easy neutrals such as white, cream, beige, or grey, for that effortlessly timeless base. Lean into earthy tones like mustard, rust, terracotta, or brown for a warmer, cosier look. Feeling bold? Pink, purple, orange, or even blue can create a confident contrast that makes your green sofa pop.
