The roles the plate doesn’t carry

Measured, before and after

  1. On the plate, the best pair of colours reads at 3.2:1: only good for large text.Falls short
  2. On screen, the text #2e211c on the background #f9f5e4 gives 14.2:1: AAA, reads with room to spare. APCA gives Lc 96: good for small text, the kind you read a paragraph of.Passes
  3. The accent #6e970b stands 3.1:1 from the background (a button needs 3:1) and as a link reaches 4.8:1 (a word needs 4.5:1).Passes
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: #f9f5e4 on 60% of the screen, #e7dfb7 on 30% (cards, bands, headers) and #6e970b 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 3.2:1). That is why body text goes in #2e211c, a near-neutral ink tinted with the palette's hue: it is not in the book, and it is needed.
  3. The buttonThe accent #6e970b stands 3.1:1 apart from the background: it works as a button, with text in #2e211c.
  4. TemperatureWarm and cool together: let one lead and the other point. Here the background #e7dfb7 leads, and the accent #6e970b is the first thing the eye will look for.
  5. How manyFour colours demand discipline: #e7dfb7 and #cf360f are the base, the other two are detail. If in doubt, drop the support colour before the accent.
  6. In the dictionaryIn the dictionary it sits among the tone-on-tone sets: colours from one family. Hierarchy comes from light, not hue, so order elements from lightest to darkest. It is one of the light ones: works on white and on screen; in print it loses body, so push the ink a notch.

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 whole palette sits on the active side of the circle: the colours that advance, warm and push outward.

  • Surface · yellow

    Yellow across a large surface is a gamble. It is the least forgiving colour: the slightest drift towards green turns gold into dirt, and on screen that drift is supplied by compression or a gradient. § 770

  • Accent · yellow

    Yellow points, but it loses the moment the ground stops being smooth and bright. On screen that means shadows, gradients and small type on top. § 771

  • Heading · orange

    Orange in a small patch is the accent that needs no explaining: it advances, it is seen, and it does not need size to do it. § 775

How each pair readsZur Farbenlehre · 1810

How each pair reads on the circle

  • Adjacent #f8f0c8 · #e94e24

    Adjacent on the circle, with no colour between them to keep them apart. They are saved by proportion: one has to lead and the other to follow. § 828

  • Same sector #f8f0c8 · #bad266

    Both fall in the same sector of the circle. There is no hue contrast, so whatever separates them will have to be lightness. § 832

    This verdict is ours. Goethe judges four of the six pairs in this group and says so himself, or one of the two colours sits right between two sectors of the circle.

  • Same sector #f8f0c8 · #8fbf21

    Both fall in the same sector of the circle. There is no hue contrast, so whatever separates them will have to be lightness. § 832

    This verdict is ours. Goethe judges four of the six pairs in this group and says so himself, or one of the two colours sits right between two sectors of the circle.

  • Adjacent #e94e24 · #bad266

    Adjacent on the circle, with no colour between them to keep them apart. They are saved by proportion: one has to lead and the other to follow. § 828

    This verdict is ours. Goethe judges four of the six pairs in this group and says so himself, or one of the two colours sits right between two sectors of the circle.

  • Adjacent #e94e24 · #8fbf21

    Adjacent on the circle, with no colour between them to keep them apart. They are saved by proportion: one has to lead and the other to follow. § 828

    This verdict is ours. Goethe judges four of the six pairs in this group and says so himself, or one of the two colours sits right between two sectors of the circle.

  • Same sector #bad266 · #8fbf21

    Both fall in the same sector of the circle. There is no hue contrast, so whatever separates them will have to be lightness. § 832

    This verdict is ours. Goethe judges four of the six pairs in this group and says so himself, or one of the two colours sits right between two sectors of the circle.

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.

Chapter 3

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.

    Move the lightness, not the hue

Plate III · The six, drawnWith Wada combination 326
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.
background heretext 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 · 14.2:1
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 · no hue here to lose
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.
