roomephantInterior color palettes: the 60-30-10 rule with ready schemes
Give 60% of the room to a base colour (walls, floor, large surfaces), 30% to a supporting one (furniture, curtains, rugs) and 10% to an accent (cushions, art, a lamp). The proportion matters more than the specific colours: the same three shades in equal parts read as chaos.
Why proportion beats colour choice
Rooms rarely fail because a colour was wrong; they fail because three colours got equal weight and none of them leads. The 60-30-10 split gives the eye a place to rest and one place to look. Once the proportion is right, a surprisingly wide range of palettes works.
Warm neutral with terracotta
The forgiving one: warm off-white walls, oak and linen for the supporting third, terracotta in cushions and ceramics. Works in north-facing rooms, where cool greys turn grim.
Cool grey with graphite
Calm and slightly formal. Keep the accent genuinely small — graphite spreads fast, and past 10% the room stops feeling airy and starts feeling like an office.
Dark base with green and brass
For rooms with plenty of daylight or plenty of lamps. A dark base needs layered light — one ceiling fixture will make it read as a cave rather than as a decision.
The usual mistakes
Three strong colours in equal parts; an accent that quietly grows to a third of the room; and picking the palette from a screen instead of from the two big things you already own — the floor and the sofa. Start from those, then choose.
Seeing beats imagining: try a piece in your room before committing to the colour, and check what colour rug goes with your couch for the pairing that trips people up most.
FAQ
What is the 60-30-10 rule?
60% of the room in a base colour, 30% in a supporting one, 10% in an accent. It is about proportion, not about which colours you pick.
How many colours should a room have?
Three is the workable default: base, supporting and accent. More than that needs one of them to clearly dominate, or the room reads as noise.
Where do I start if the floor is already dark?
Treat the floor as part of the 60% base and choose walls that keep it company rather than fight it. Picking a palette that ignores the floor is the most common way rooms end up incoherent.
