What each one is.

The hex codes come from the book's CMYK run through the FOGRA39 press profile. Under each colour we also list the hex other websites use, which comes from a direct formula and oversaturates.

The same hue as the plate with the lightness moved to where an interface needs it: the background rests, the surface keeps the colour from the book and the accent earns the button. Each role says which colour it comes from and what was done to it. Click any to copy.

  • 60% BackgroundWhere the eye rests: most of the screen. The plate's #a8262e, darkened.
  • 30% SurfaceCards, bands, headers. This is where the book's colour lives. From the plate, as is (#a8262e).
  • 10% AccentOnly what gets clicked. The plate's #0066b0, lightened.

The roles the plate doesn’t carry

Measured, before and after

  1. On the plate, the best pair of colours reads at 1.1:1: does not read.Falls short
  2. On screen, the text #eaeef7 on the background #301c1b gives 13.8:1: AAA, reads with room to spare. APCA gives Lc 94: good for small text, the kind you read a paragraph of.Passes
  3. The accent #1f70bb stands 3.1:1 from the background (a button needs 3:1) and as a link reaches 4.7:1 (a word needs 4.5:1).Passes
  4. Under deuteranopia, your accent and your background drop to 2.8:1. The button stops standing out: give it a border, change the lightness, or don't rely on colour alone to mark it.Falls short
Out in the worldAdapted

This is the plate with a whole screen to fill.

This paragraph is here so you can see real text on a real background, which is where half of the pretty palettes fall over. If it's hard to read, now you know. And this is a link.

A card

Secondary surfaces use the support colour. If it doesn't separate from the background, the hierarchy is gone.

Adapted: the background rests, the surface keeps the plate’s colour and the accent earns the button.

How to use it

  1. ProportionDistribute, don't equalise: #301c1b on 60% of the screen, #a8262e on 30% (cards, bands, headers) and #1f70bb on 10%, only on buttons and links. A colour loses force the more surface it covers; what looks intense on the plate softens at full screen.
  2. TextNo pair on the plate read as text (the best gave 1.1:1). That is why body text goes in #eaeef7, a near-neutral ink tinted with the palette's hue: it is not in the book, and it is needed.
  3. The buttonThe accent #1f70bb stands 3.1:1 apart from the background: it works as a button, with text in #fff4f3.
  4. TemperatureWarm and cool together: let one lead and the other point. Here the background #a8262e leads, and the accent #1f70bb is the first thing the eye will look for.
  5. How manyTwo colours are a pair, not a brand: add a neutral (an off-white or a grey) to get background, text and accent without straining either.
  6. In the dictionaryIn the dictionary it sits among the contrasting-hue sets: hues deliberately set against each other. The contrast is already there; don't force it with shadows or blacks. It is one of the dense ones: loaded colours that need plenty of air around them; less is more.

Goethe’s readingWhat it conveys

What this combination conveys, and why.

Wada tells you which colours go together. Goethe, a century earlier, explains why a combination means something or means nothing, and what each colour does depending on how much of the screen it takes. His circle has six colours and three oppositions, and every verdict below carries the paragraph it comes from.

What it conveys, by where each colour landed

The palette crosses both sides of the circle, active and passive. It carries the most tension and most needs one of the two to lead.

  • Surface · red

    Red at full surface leaves room for nothing else. It is the colour of gravity and dignity, and in a background that reads as constant weight. § 790

  • Accent and Heading · blue

    Blue recedes, and an accent is asked to do the opposite. As a link it only has to be distinguishable; as a primary button it needs contrast to do the work the colour will not. § 781

What is happening to this palette

  1. There is nowhere for the eye to rest: no neutral, no muted colour, no green. The whole palette asks for attention at once. § 802

  2. There are 5 points of lightness between the lightest and darkest colour. With no step in lightness there is no hierarchy: the palette leans entirely on hue, and hue alone does not order a screen. § 849

How each pair readsZur Farbenlehre · 1810

How each pair reads on the circle

  • Characteristic #a8262e · #0066b0

    Blue and red, with violet skipped. It approaches the effect of the violet their mixture would produce. § 821

Criteria taken from Zur Farbenlehre (1810), in Eastlake's 1840 translation, which is public domain. The explanations are ours: from a book you take the substance, not the wording. The light values usually credited to Goethe for working out surface proportions are not in the Farbenlehre — they are Itten's, 1961, and that is how they are credited in the adaptation rules.

From plate to screen: six rules that are not ours

Wada worked with ink. You work with light.

Wada designed for ink, cloth and pigment. A screen emits light, is read for minutes at a time and has a law. These are the rules colour for interfaces is built with, and the ones we adapt each plate with; none of them is ours, so each one carries its owner.

Plate III · The six, drawnWith Wada combination 51
In the book · equal partsOn screen · 60 · 30 · 10
One colour dominates, another accompanies and the third only points. In the book they sit in equal parts because that is how you compare them; on screen, equalising them is noise. Itten measured it in 1961: complementaries balance in areas inverse to their strength.
text herebackground here
The background lives at one end of the lightness scale, very light or very dark, with little colour. Neither pure white nor pure black: tinted with the palette's hue, which is what separates a designed interface from an assembled one.
Surface · 30%
Cards, bands and headers are the 30%: that is where Wada's colour shows at full size without carrying a paragraph. Material separates a colour from its role, “surface” and “on-surface”, so the hue can change without touching the interface.
A whole paragraph in the book's colour tires you out by the third line.Accent on background · 3.1:1In the tinted ink it reads without a second thought.Text on background · 13.8:1
Long text goes in a near-black (or near-white) tinted with the palette's hue, at 7:1. The book's colours enter through headings, where size forgives. GOV.UK writes in #0b0c0c, not #000.
Book a slotAccent / background · 3.1:1Good for a button
The most saturated colour goes only on what gets clicked, and is held to what the law asks of a component: 3:1 against the background (WCAG 1.4.11). As a word, 4.5:1 (1.4.3): a button and a link are not the same thing, and Radix gives them two different steps of its scale.
Lab · the hue stays putHSL · the hue drifts 12°
Every adjustment is a change of lightness in a perceptual space (Lab, OKLCH): the hue stays put. In HSL, darkening a blue turns it violet and lightening it turns it lilac.

Colophon

Colour is where it starts, not the whole job

If it is for your brand, this is what we do: custom websites that start with colour and end in code.

And something Wada already warned about back then: the plate is not the application. His samples sit on equal surfaces only so they can be compared. On a website the background leads, the text reads and the accent points, and a colour loses strength the more surface it covers. That is why every palette comes with its roles and some advice, not four equal squares.

Combinations based on Sanzō Wada's system (Haishoku Sōkan, 1933-34; Seigensha selection, 2010). Colour values are checked against that edition; the Spanish names, each combination's character and the explanations are ours.
