Colour stories

Why obsidian is a clean reference for charcoal

Obsidian is volcanic glass that cools too fast for mineral crystals to form. With no crystal structure to scatter light unpredictably, it reaches a genuinely neutral, near-black colour rather than a very dark shade of some other hue.

In practice: It's a useful comparison point for judging whether a 'black' material actually carries a colour cast — like charcoal's subtle blue undertone — or is close to truly neutral.

Uses & contexts

Often confused with

Using this colour in a real room

Using charcoal 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 large-surface colour. At chroma 9 it is restrained enough to cover a lot of ground without tiring, and too quiet to work as an accent.

• Walls and large surfaces

  strong

  Chroma 9 sits inside the range walls and large surfaces carry without taking over the room. At L*28 it also absorbs a good deal of the light in the room, so plan the lighting alongside it rather than afterwards.

• Secondary surfaces

  strong

  Chroma 9 sits inside the range secondary surfaces carry without taking over the room.

• Furniture

  strong

  Chroma 9 sits inside the range furniture carry without taking over the room.

• Rugs, curtains and bedding

  strong

  Chroma 9 sits inside the range rugs, curtains and bedding carry without taking over the room.

• Trim and joinery

  strong

  Chroma 9 sits inside the range trim and joinery carry without taking over the room.

• Accents and small objects

  difficult

  At chroma 9 this is too quiet to read as an accent — it will look like something that happened rather than something chosen.

How it behaves under different lightsensitive

Under warm bulbs

Warm bulbs emit little short-wavelength energy, so there is less for a blue to reflect. At this low chroma there is nothing in reserve, so expect it to go noticeably grey or muddy after dark.

Under cool bulbs

Cool light flatters this — it will hold its identity and may read slightly more saturated than in warm light.

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

  works well

  Opposite in undertone to Oak, and separated enough in hue that the difference reads as deliberate contrast rather than as a clash. 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

  Opposite in undertone to Walnut, and separated enough in hue that the difference reads as deliberate contrast rather than as a clash. 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

  works well

  Opposite in undertone to Pine, and separated enough in hue that the difference reads as deliberate contrast rather than as a clash. 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

  works well

  Opposite in undertone to Plywood, and separated enough in hue that the difference reads as deliberate contrast rather than as a clash. 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

  Opposite in undertone to Light wood (ash, birch, beech), and separated enough in hue that the difference reads as deliberate contrast rather than as a clash. 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

  Opposite in undertone to Dark wood, and separated enough in hue that the difference reads as deliberate contrast rather than as a clash. 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

  Opposite in undertone to Reddish wood (mahogany, cherry, teak), and separated enough in hue that the difference reads as deliberate contrast rather than as a clash. 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

  works well

  Shares Brass's cool bias, so the two agree about the temperature of the room. There is also 39 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.

• Gold-tone

  works well

  Shares Gold-tone's cool bias, so the two agree about the temperature of the room. There is also 39 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.

• Chrome

  works well

  Shares Chrome's cool bias, so the two agree about the temperature of the room. There is also 52 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 cool bias, so the two agree about the temperature of the room. There is also 48 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

  needs care

  This sits close to Black metal without matching it — near enough that the eye reads an attempted match and far enough that it fails. Either move decisively away or repeat the tone exactly.

• Copper

  works well

  Shares Copper's cool bias, so the two agree about the temperature of the room. There is also 39 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.

Where it can go wrong

• May flatten against similar neutrals. With so little chroma the only thing separating this from a neighbouring beige or grey is lightness, so anything within about fifteen points of it will merge.
• May go muddy under weak warm light. A cool colour with little chroma has nothing in reserve when the source is short of short-wavelength energy, which is the single most common complaint about pale cool greys.
