Colours, materials and moodboards: defining your interior

Most interiors go wrong one reasonable decision at a time. A paint colour here, a sofa there, a worktop later — each choice defensible on its own, yet once assembled they can leave a room with nothing much to say. What makes a space feel designed is rarely the quantity of objects; it is the coherence between three things: colour, material and the light that reveals both. That is exactly what a moodboard is for — not a pretty collage pinned above a desk, but a decision tool that settles intent before the first order is placed. This piece sets out a practical method: begin with the mood rather than a colour, give the palette a hierarchy, test tones in your own light, pair materials that answer each other, and translate the result into finishes you can genuinely order. The proportions and figures quoted are indicative rules of thumb to adapt to your home; the method is the part that holds.

A moodboard decides, it does not decorate

A useful board answers very concrete questions: which three or four materials will appear in every room? Which family of tones carries the background, and which one punctuates? How should the space feel as you walk in? If the board cannot settle a choice between two options, it is not finished. Eight to fifteen references is usually the sweet spot — enough to reveal a direction, few enough to stay legible. Fill it with close-ups of material (grain of timber, a lime plaster, a woven textile) rather than photographs of finished products, add two or three ambient shots taken in light comparable to yours, and keep physical samples within reach. One rule prevents most regrets: never approve a finish from a screen. A backlit display exaggerates contrast and cools warm tones; the sample in your hand is the one that counts.

Start with the mood, not with the colour

The commonest and costliest reflex is to choose a colour before deciding what the room should feel like. Someone falls for a deep green seen at a friend's place, applies it in a dark room, and ends up with a cellar. Mood comes first: do you want a room that soothes at the end of the day, or one that wakes you up and gives energy? Starting from what is fixed in the home avoids many mistakes, because floors, doors, windows, beams and staircases impose their own tones and are not going anywhere. Colour can then be chosen with full knowledge — not the other way round.

• Write down three adjectives for the room: bright, calm, warm — or graphic, restrained, dense.
• Start from what stays: floors, doors, windows, beams, staircase; fixed elements constrain a palette more than taste does.
• Match intensity to use: a working space tolerates less saturation than an evening living room.
• Keep one thread: a signature material or tone repeated unifies better than a pile of effects.

Give the palette a hierarchy: 60, 30, 10

A convention borrowed from the fit-out trade keeps schemes from turning into a showroom: roughly 60 % background tones, 30 % secondary, 10 % accent. In an apartment that usually means a neutral — off-white, greige, beige, a heavily desaturated sage — across most vertical surfaces; timber, stone or a strong textile in the secondary role; and an accent (brass, terracotta, deep blue, matte black) kept to a detail: a piece of hardware, one panel, one chair. This hierarchy forbids nothing; it puts things in order, and that order is what produces calm in an interior that may still be rich in materials.

• Base (about 60 %): walls, large volumes, ceiling — calm tones that age well.
• Secondary (about 30 %): timber, stone, textile, furniture — the material that gives character.
• Accent (about 10 %): metal, strong colour, gloss — the detail that pulls the eye and structures the room.
• One dominant accent only: several competing notes scatter the eye and wear it out.

You do not paint a room so that it looks good in a photograph, but so that it feels right at seven in the morning and nine at night. Colour is chosen with the hours you will spend inside it.

Light changes everything

Two flats can take the same paint and look nothing alike. A tone shifts with orientation, with the greenery outside the window, with the colour temperature of the lamps and with the grain of the surface. A north-facing room receives cool, often bluish light: neutral greys and pure whites go flat there, while warm off-whites, sand and soft mustard hold the mood. A south-facing room, generously washed in light, carries cooler tones and crisp whites comfortably. In the evening, artificial light that is too cool — above roughly 3000 K — hardens a warm interior; in living spaces it is worth aiming nearer 2700 K. The reliable method remains thoroughly analogue: paint a large board, or a patch of about 60 × 60 cm on the wall, and watch it for two days at three different hours before ordering.

Pairing materials: contrast as the binding agent

A palette without materials stays abstract; it is the way surfaces meet that reads as quality. Three families usually suffice to structure an interior: something alive (timber, linen, wool, leather), something hard or mineral (stone, ceramic, glass, metal), and a neutral binder (matte paint, plaster, microcement). Build on a legible contrast: matte against gloss, warm against cool, smooth against textured. Two dominant materials plus a third as accent hold together; beyond four or five the eye loses the thread. Think about touch as well — a stone worktop and a timber one do not feel the same in daily use. And be honest about maintenance: a surface that asks for ten minutes a week must genuinely please you.

A few simple reference points help you decide: two dominant materials and one accent material, no more; matched temperatures — pale blonde timber sits naturally with cool greys, walnut or smoked oak calls for warmer whites; contrasts played in pairs, matte and gloss, smooth and textured, mineral and vegetal; and a physical sample of every finish, edges and profiles included.

From moodboard to order

The decisive moment is the move from intention to purchase order. A validated board becomes a technical document: tones with manufacturer references, a material plan element by element (carcass, fronts, worktop, edge, hardware) and finish samples at the scale of the actual piece. For bespoke joinery, approve at least a front sample and a worktop sample — one and the same shade behaves differently on a vertical panel and on a horizontal surface catching raking light. This is also when to think about continuity: in a through living room or an open kitchen, a material running across two spaces does more for cohesion than any wallpaper. One last caution: high-gloss finishes over large areas. Superb behind a shop window, more demanding at home, because they show every reflection.

A coherent interior is nothing mysterious: a handful of materials held consistently, a palette with hierarchy, tones approved in real light. The proportions, colour temperatures and ranges above are indicative working reference points to adapt to your own home, and each finish is worth confirming on a physical sample. For context, the Swiss construction and housing statistics of the Federal Statistical Office (https://www.bfs.admin.ch/bfs/en/home/statistics/construction-housing.html) document the housing stock and building activity, the Hausinfo portal (https://www.hausinfo.ch/en/home.html) gathers practical guidance on materials and looking after a home, and Egger (https://www.egger.com) documents panel and decor ranges — a useful picture of the finishes actually available on the market.
