Colour stories

Why rose quartz and amethyst are the same mineral, different colours

Rose quartz and amethyst are both varieties of quartz — silicon dioxide with the same crystal structure. Trace titanium, manganese or microscopic mineral fibres tint quartz pink; trace iron, altered by natural background radiation over geological time, tints it purple instead.

In practice: Colour in minerals often comes down to which trace element got trapped in the crystal as it grew, not a fundamentally different material — a useful reminder that a name like 'quartz' describes structure, not colour.

Uses & contexts

Using purple in a real space

Worked out from this colour’s own measurements — its lightness, saturation and undertone — rather than written for it. That is why the guidance differs from one colour to the next even when the two look similar.

What role it can play

This is a small-scale colour. At chroma 69 it holds attention easily, which is a strength on a cushion or a door and a liability across four walls.

• Walls and large surfaces

  difficult

  At chroma 69 this is far above the level walls and large surfaces usually carry comfortably. It can be done deliberately, but it will be the room rather than part of it.

• Secondary surfaces

  workable

  Chroma 69 is above the usual comfort level for secondary surfaces, so expect it to take charge. That is a legitimate choice in a room that wants a subject. On panelling, a chimney breast or an alcove this is semi-permanent — repaintable, but not casually.

• Furniture

  workable

  Chroma 69 is above the usual comfort level for furniture, so expect it to take charge. That is a legitimate choice in a room that wants a subject. In a sofa or a cabinet this is one purchase you will live with, so it is worth seeing the piece in the actual room first.

• Rugs, curtains and bedding

  workable

  Chroma 69 is above the usual comfort level for rugs, curtains and bedding, so expect it to take charge. That is a legitimate choice in a room that wants a subject. In rugs, curtains and bedding it is the cheapest commitment in the room to reverse, which makes it the right place to test a strong colour.

• Trim and joinery

  strong

  Chroma 69 sits inside the range trim and joinery carry without taking over the room.

• Accents and small objects

  strong

  Chroma 69 is exactly what an accent is for. The saturation that makes this difficult across a wall is the reason it works on a cushion, a door or a single chair.

How it behaves under different lightresilient

Under warm bulbs

With almost no hue of its own, this mostly reports the colour of the light. Under warm bulbs it will read warm — which is not the colour changing but the colour being honest.

Under cool bulbs

Near-neutral under any source, so a cool bulb will simply make it read cool.

In daylight

Deep colours hold their identity in daylight better than pale ones, because there is more of the range left to work in. This will look most like itself in good indirect light.

In a dim room

At low light levels the eye's colour discrimination genuinely falls and deep colours converge toward each other. This will read as "dark" rather than as its own colour in a dim room unless it is lit.

Compared with the sample card

Already deep, so there is little further to fall — but on a large matte surface it will absorb enough light to look flatter than the sample.

What colour temperature actually means · Why two bulbs at the same rating can differ

With wood

• Oak

  needs care

  Shares Oak's neutral bias, but at chroma 69 against a material that already carries colour of its own, the two compete rather than combine. It works when this colour is confined to a small area and fails when both are large. The amount of timber matters as much as the tone: one piece is an accent, a floor plus joinery is the room's dominant colour.

• Walnut

  works well

  Shares Walnut's neutral bias, so the two agree about the temperature of the room. They sit close in depth, so expect a quiet, tonal relationship rather than a contrast. The amount of timber matters as much as the tone: one piece is an accent, a floor plus joinery is the room's dominant colour.

• Pine

  needs care

  Shares Pine's neutral bias, but at chroma 69 against a material that already carries colour of its own, the two compete rather than combine. It works when this colour is confined to a small area and fails when both are large. The amount of timber matters as much as the tone: one piece is an accent, a floor plus joinery is the room's dominant colour.

• Plywood

  needs care

  Shares Plywood's neutral bias, but at chroma 69 against a material that already carries colour of its own, the two compete rather than combine. It works when this colour is confined to a small area and fails when both are large. The amount of timber matters as much as the tone: one piece is an accent, a floor plus joinery is the room's dominant colour.

• Light wood (ash, birch, beech)

  works well

  Shares Light wood (ash, birch, beech)'s neutral bias, so the two agree about the temperature of the room. There is also 56 points of lightness between them, which keeps the two readable as separate elements. The amount of timber matters as much as the tone: one piece is an accent, a floor plus joinery is the room's dominant colour.

• Dark wood

  works well

  Shares Dark wood's neutral bias, so the two agree about the temperature of the room. They sit close in depth, so expect a quiet, tonal relationship rather than a contrast. The amount of timber matters as much as the tone: one piece is an accent, a floor plus joinery is the room's dominant colour.

• Reddish wood (mahogany, cherry, teak)

  works well

  Shares Reddish wood (mahogany, cherry, teak)'s neutral bias, so the two agree about the temperature of the room. They sit close in depth, so expect a quiet, tonal relationship rather than a contrast. The amount of timber matters as much as the tone: one piece is an accent, a floor plus joinery is the room's dominant colour.

With metal fittings

• Brass

  needs care

  Shares Brass's neutral bias, but at chroma 69 against a material that already carries colour of its own, the two compete rather than combine. It works when this colour is confined to a small area and fails when both are large. Metal carries more attention than its area suggests, so repetition matters more than the exact finish.

• Gold-tone

  needs care

  Shares Gold-tone's neutral bias, but at chroma 69 against a material that already carries colour of its own, the two compete rather than combine. It works when this colour is confined to a small area and fails when both are large. Metal carries more attention than its area suggests, so repetition matters more than the exact finish.

• Chrome

  works well

  Shares Chrome's neutral bias, so the two agree about the temperature of the room. There is also 51 points of lightness between them, which keeps the two readable as separate elements. Metal carries more attention than its area suggests, so repetition matters more than the exact finish.

• Stainless steel

  works well

  Shares Stainless steel's neutral bias, so the two agree about the temperature of the room. There is also 46 points of lightness between them, which keeps the two readable as separate elements. Metal carries more attention than its area suggests, so repetition matters more than the exact finish.

• Black metal

  works well

  Shares Black metal's neutral bias, so the two agree about the temperature of the room. There is also 23 points of lightness between them, which keeps the two readable as separate elements. Metal carries more attention than its area suggests, so repetition matters more than the exact finish.

• Copper

  needs care

  Shares Copper's neutral bias, but at chroma 69 against a material that already carries colour of its own, the two compete rather than combine. It works when this colour is confined to a small area and fails when both are large. Metal carries more attention than its area suggests, so repetition matters more than the exact finish.

Where it can go wrong

• May dominate a small or dim room. At L*30 and chroma 69 it absorbs light and holds attention at the same time, which is a lot to ask of a space that has little of either.
