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 #541942, darkened.
- 30% SurfaceCards, bands, headers. This is where the book's colour lives. From the plate, as is (#541942).
- 10% AccentOnly what gets clicked. The plate's #43763b, lightened.
The roles the plate doesn’t carry
Measured, before and after
- On the plate, the best pair of colours reads at 8.0:1: AAA, reads with room to spare.Passes
- On screen, the text #eeeee8 on the background #2d1c27 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 #487b40 stands 3.2:1 from the background (a button needs 3:1) and as a link reaches 4.5:1 (a word needs 4.5:1).Passes
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: #2d1c27 on 60% of the screen, #541942 on 30% (cards, bands, headers) and #487b40 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.
- TextBody text goes in #eeeee8, a near-neutral ink tinted with the palette's hue, even though the plate had a pair that read: a saturated colour as text tires by the third line. The book's colour enters through the heading, in #cdcd9b, where size forgives.
- The buttonThe accent #487b40 stands 3.2:1 apart from the background: it works as a button, with text in #fdf4f9.
- TemperatureWarm and cool together: let one lead and the other point. Here the background #541942 leads, and the accent #487b40 is the first thing the eye will look for.
- How manyFour colours demand discipline: #541942 and #eeeee8 are the base, the other two are detail. If in doubt, drop the support colour before the accent.
- 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 mixed-light ones: it already brings hierarchy. Keep it on screen: lightest at the back, darkest in front.
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 · green
Green is the colour of rest, so as an accent it points at nothing: the eye accepts it and moves on. If this palette needs something to stop the eye, this is not it. § 802
- Heading · 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
How each pair reads on the circle
- Adjacent #cdcd9b · #43763b
Adjacent on the circle, with nothing between them. Ordinary and agreeable: it says little, and it does not offend. § 829
- With a neutral #cdcd9b · #2f3525
Next to black, a colour from the active side gains energy. § 831
- Opposite #cdcd9b · #541942
Opposite on the circle: together they complete what the eye asks for on its own. It is the only category Goethe approves without reservation. § 810
- With a neutral #43763b · #2f3525
A neutral with a colour that has no side on the circle. Goethe has nothing to say here. § 831
- Characteristic #43763b · #541942
Characteristic by geometry — there is a colour skipped between the two. But Goethe judges only four pairs in this group, and this is not one of them. § 823
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.
- With a neutral #2f3525 · #541942
Next to black, a colour from the passive side loses. § 831
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.
