60-30-10 rule.

What it means in interior design.

The 60-30-10 rule is a rule of thumb for colour proportion: about 60% dominant colour, 30% secondary and 10% accent. It describes how much of each colour a room shows, not how many colours it has.

In practice

The dominant is usually walls and large floor areas, the secondary furniture and textiles, the accent small objects. Repeat the accent about three times across the room so it reads as intended.

Hue

Hue is a colour’s family: red, yellow, blue-green and so on, its position on the colour wheel. It is what most people mean by “colour”, and usually the least important of the three dimensions in a room.

Value

Value is how light or dark a colour is, independent of its hue. A pale blue and a pale pink can share the same value.

Saturation

Saturation (or chroma) is a colour’s intensity: how far it is from grey. High saturation is vivid; low saturation is muted, dusty or greyed.

Complementary colours

Complementary colours sit opposite each other on the colour wheel, such as blue and orange or red and green. Placed together they intensify each other; mixed, they neutralise to grey.

Analogous colours

Analogous colours sit next to each other on the colour wheel, such as yellow-green, green and blue-green. They share a common hue, so they harmonise easily.

Anthropometrics

Anthropometrics is the measurement of the human body: heights, reaches, widths and how they vary between people. It is the data behind every seat height, worktop and doorway.

Proxemics

Proxemics is the study of how people use distance between one another, described by the anthropologist Edward T. Hall. He named four zones: intimate (to 45 cm), personal (45–120 cm), social (1.2–3.6 m) and public (beyond).

Plan

A plan is a horizontal section through a building, cut about 1.2 m above the floor and viewed from above. Cut walls are drawn heaviest or filled; everything below the cut is drawn lighter.

Section

A section is a vertical cut through a building or room, taken along a line marked on the plan. It shows heights and levels: ceilings, floors, sills, steps and the spaces between them.
