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.

Adapted for screen
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 #592363, darkened.
- 30% SurfaceCards, bands, headers. This is where the book's colour lives. From the plate, as is (#592363).
- 10% AccentOnly what gets clicked. The plate's #93495f, lightened.
The roles the plate doesn’t carry
Measured, before and after
- On the plate, the best pair of colours reads at 2.4:1: does not read.Falls short
- On screen, the text #eeeeef on the background #291e2b gives 13.7:1: AAA, reads with room to spare. APCA gives Lc 94: good for small text, the kind you read a paragraph of.Passes
- The accent #a4586e stands 3.1:1 from the background (a button needs 3:1) and as a link reaches 4.5:1 (a word needs 4.5:1).Passes
- Under protanopia, 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
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.
How to use it
- ProportionDistribute, don't equalise: #291e2b on 60% of the screen, #592363 on 30% (cards, bands, headers) and #a4586e 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.
- TextNo pair on the plate read as text (the best gave 2.4:1). That is why body text goes in #eeeeef, a near-neutral ink tinted with the palette's hue: it is not in the book, and it is needed.
- The buttonThe accent #a4586e stands 3.1:1 apart from the background: it works as a button, with text in #fbf5fb.
- TemperatureWarm and cool together: let one lead and the other point. Here the background #592363 leads, and the accent #a4586e is the first thing the eye will look for.
- How manyThree colours is the comfortable measure: background, text and one accent. Don't add a fourth unless it earns its place by contrast or by hue.
- 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 dark ones: it needs light text and large surfaces; in small pieces it clogs.
The kit
A brand needs four colours; an interface needs a good deal more. This is what you'd otherwise invent by hand once you take four hex codes into the editor.

The palette is born dark; this is its light version. The background is not pure white: it carries a little of its hue, just as the dark one was not black.

}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 · violet
Goethe puts it bluntly: a large surface of pure violet would be intolerable. It holds up here because the screen adaptation has taken the chroma down. On the plate, at full saturation, it would not. § 790
- Accent · red
Red is the high point of the active side. In a small patch it does exactly what an accent is for: stopping the eye once. § 793
How each pair reads on the circle
- With a neutral #75737d · #93495f
Next to black, a colour from the active side gains energy. § 831
- With a neutral #75737d · #592363
Next to black, a colour from the passive side loses. § 831
- Adjacent #93495f · #592363
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
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.

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.
