Aquamarine

Uses & contexts

Nearest named colours, and how they differ

• Seafoam Green is the closest, at ΔE00 8.3 from aquamarine: 7 points darker, 16 points less saturated and 8° round towards yellow. That is clearly different, though many people would use one name for both.

• Turquoise is next, at ΔE00 10.7 from aquamarine: 11 points darker, 2 points less saturated and 17° round towards green. That is clearly different, though many people would use one name for both.

• Mint Green is next, at ΔE00 13.0 from aquamarine: 17 points more saturated and 27° round towards yellow. That is a different colour at a glance.

• Cyan is next, at ΔE00 14.0 from aquamarine: 4 points more saturated and 28° round towards green. That is a different colour at a glance.

Distances are CIEDE2000 between catalogue reference values; lightness and saturation are CIELAB L* and C*. How to read a ΔE figure · Measure any two colours

Using aquamarine 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 47 it is assertive enough to register on a small object and restrained enough not to dominate a wall.

• Walls and large surfaces

  workable

  Chroma 47 is above the usual comfort level for walls and large surfaces, so expect it to take charge. That is a legitimate choice in a room that wants a subject. Walls set the room's baseline, so this is the decision everything else answers to.

• Secondary surfaces

  strong

  Chroma 47 sits inside the range secondary surfaces carry without taking over the room.

• Furniture

  strong

  Chroma 47 sits inside the range furniture carry without taking over the room.

• Rugs, curtains and bedding

  strong

  Chroma 47 sits inside the range rugs, curtains and bedding carry without taking over the room.

• Trim and joinery

  strong

  Chroma 47 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 47 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

Warm bulbs emit little short-wavelength energy, so there is less for a green to reflect. There is enough chroma here to survive it, though it will read warmer and slightly duller.

Under cool bulbs

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

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

• Walnut · Dark wood · Reddish wood (mahogany, cherry, teak)

  works well

  Opposite in undertone to Walnut, Dark wood and Reddish wood (mahogany, cherry, teak), but 64–70 points apart in lightness or far enough round the hue circle that the difference reads as deliberate contrast rather than as a clash.

• Oak · Pine · Plywood · Light wood (ash, birch, beech)

  needs care

  Opposed in undertone to Oak, Pine, Plywood and Light wood (ash, birch, beech) with only 6–26 points of lightness to explain the difference, which is the combination the eye most often reads as an error.

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. More on working with wood tones

With metal fittings

• Brass · Gold-tone · Black metal · Copper

  works well

  Shares the cool bias of Brass, Gold-tone, Black metal and Copper, so they agree about the temperature of the room, and 24–85 points of lightness keep them readable as separate from this colour.

• Chrome · Stainless steel

  works well

  Shares the cool bias of Chrome and Stainless steel and sits within 11–16 points of them in lightness, 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. More on metals and mixing them

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.
