The 60-30-10 rule: the proportion that brings order to colour
Why splitting three colours equally doesn't decorate, and how to use the 60-30-10 proportion so your living room feels calm.

How it looks in Casa Garpe
Sound familiar? You paint, you shop, you arrange… and the living room still doesn’t “feel right”. It’s rarely the colour itself. It’s almost always how much of each one there is.
The usual mistake
Picking three colours you love and splitting them equally: a third each. It looks balanced on paper, but the result is a room where all three compete and none leads. The eye has nowhere to rest and the space feels restless, even if every piece is beautiful on its own.
The proportion
The 60-30-10 rule isn’t a law; it’s a starting point that works very well in real homes:
- 60 · Dominant colour. Walls, floor and large surfaces. Keep it calm: it leads, so it doesn’t need to shout. In a Mediterranean key it’s usually a warm white, linen or sand.
- 30 · Secondary colour. Sofa, curtains, rug, a large piece of furniture. It supports the dominant colour without competing and gives the room its character.
- 10 · Accent colour. Cushions, ceramics, a print, a plant in a clay pot. Here, be brave. It’s small on purpose, and that’s why it shows.
The percentages are a guide. What matters is the hierarchy: one leads, one supports and the last one sparks.
How we applied it in Casa Garpe
In our own living room the split looks like this:
- 60: linen on the walls and curtains, and the light oak floor. Everything that covers the most surface is light and warm.
- 30: the walnut slat panel and the midnight blue sofa. They’re the two pieces that give the room weight and personality.
- 10: terracotta dining chairs and a mustard cushion. Small, but they’re the first thing you notice.
Midnight blue isn’t an “easy” colour. It works because it’s in the right place: in the 30, surrounded by plenty of linen, with a warm accent that softens it.
Use it today
- Name your 60. Look at your living room and say out loud which colour covers the most surface. Is it the one you want leading? If not, start there before buying anything.
- Check your 30. If your sofa, curtains and rug are three different colours, pick one for the 30 and move the others towards the 60 or the 10.
- Remove before you add. If there are accents everywhere, take away half. The 10 works because it’s small.
- Repeat the accent two or three times. One terracotta cushion looks like a mistake; a cushion, a ceramic and a print in the same tone look like a decision.
- Check the room at night. Warm light changes colours. Make sure your 60 still feels calm.
One last tip
The rule helps you organise, not decide for you. If a colour makes you happy, find its percentage instead of giving it up.
