Butter Yellow

Uses & contexts

Using butter yellow 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 works across a range of sizes. At chroma 31 it is assertive enough to register on a small object and restrained enough not to dominate a wall.

• Walls and large surfaces

  strong

  Chroma 31 sits inside the range walls and large surfaces carry without taking over the room.

• Secondary surfaces

  strong

  Chroma 31 sits inside the range secondary surfaces carry without taking over the room.

• Furniture

  strong

  Chroma 31 sits inside the range furniture carry without taking over the room.

• Rugs, curtains and bedding

  strong

  Chroma 31 sits inside the range rugs, curtains and bedding carry without taking over the room.

• Trim and joinery

  strong

  Chroma 31 sits inside the range trim and joinery carry without taking over the room. Its lightness makes it a conventional trim choice, which is a strength when the walls should be the subject.

• Accents and small objects

  strong

  Chroma 31 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 lightmoderate

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

In strong daylight a colour this light approaches the top of its range, and differences between it and other pale colours compress. It can look washed out at midday in a south-facing room and return in the evening.

In a dim room

Enough lightness and chroma to stay recognisable in a dim room, though it will lose some saturation.

Compared with the sample card

Pale colours almost always read darker in place than on a card, because a card is seen against white and a wall is seen against itself. Expect a step down.

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

With wood

• Oak

  works well

  Shares Oak's neutral bias, so the two agree about the temperature of the room. There is also 29 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.

• Walnut

  works well

  Shares Walnut's neutral bias, so the two agree about the temperature of the room. There is also 67 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.

• Pine

  needs care

  This sits close to Pine 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.

• Plywood

  needs care

  This sits close to Plywood 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.

• Light wood (ash, birch, beech)

  needs care

  This sits close to Light wood (ash, birch, beech) 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.

• Dark wood

  works well

  Shares Dark wood's neutral bias, so the two agree about the temperature of the room. There is also 73 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.

• 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. There is also 67 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.

With metal fittings

• Brass

  works well

  Shares Brass's neutral bias, so the two agree about the temperature of the room. There is also 27 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 neutral bias, so the two agree about the temperature of the room. There is also 27 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 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. 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. They sit close in depth, so expect a quiet, tonal relationship rather than a contrast. 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 88 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

  works well

  Shares Copper's neutral bias, so the two agree about the temperature of the room. There is also 27 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 show every imperfection. Very light surfaces reveal uneven plaster, patching and marks that a mid-tone hides, so the substrate matters more than usual.
