Powder Blue

Uses & contexts

Nearest named colours, and how they differ

• Duck Egg Blue is the closest, at ΔE00 4.0 from powder blue: 2 points lighter, 5 points less saturated and 3° round towards green. That is visibly different side by side, easily confused apart.

• Sky Blue is next, at ΔE00 9.2 from powder blue: 7 points darker, 10 points more saturated and 26° round towards blue. That is clearly different, though many people would use one name for both.

• Azure is next, at ΔE00 12.0 from powder blue: 13 points lighter and 11 points less saturated. That is clearly different, though many people would use one name for both.

• Ash Grey is next, at ΔE00 13.2 from powder blue: 10 points darker and 10 points less saturated. 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 powder blue 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 16 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 16 sits inside the range walls and large surfaces carry without taking over the room.

• Secondary surfaces

  strong

  Chroma 16 sits inside the range secondary surfaces carry without taking over the room.

• Furniture

  strong

  Chroma 16 sits inside the range furniture carry without taking over the room.

• Rugs, curtains and bedding

  strong

  Chroma 16 sits inside the range rugs, curtains and bedding carry without taking over the room.

• Trim and joinery

  strong

  Chroma 16 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

  difficult

  At chroma 16 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 lightmoderate

Under warm bulbs

Warm bulbs emit little short-wavelength energy, so there is less for a cyan 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

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 58–64 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 0–20 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

• Black metal

  works well

  Shares the cool bias of Black metal, so they agree about the temperature of the room, and 79 points of lightness keep it readable as separate from this colour.

• Brass · Gold-tone · Copper

  works well

  Shares the cool bias of Brass, Gold-tone and Copper and sits within 18 points of them in lightness, so expect a quiet, tonal relationship rather than a contrast.

• Chrome · Stainless steel

  needs care

  Sits close to Chrome and Stainless steel without matching them (ΔE00 15) — near enough that the eye reads an attempted match and far enough that it fails. Either move decisively away or repeat the tone exactly.

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 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.
