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.

This is where the in-betweens the plate doesn’t carry come from: borders, card backgrounds, disabled states. The mix is done in OKLab, which is closer to mixing paint than to averaging numbers. Click the result to copy it.
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 #00aa95, lightened.
- 30% SurfaceCards, bands, headers. This is where the book's colour lives. From the plate, as is (#00aa95).
- 10% AccentOnly what gets clicked. The plate's #d84c5a, darkened.
The roles the plate doesn’t carry
Measured, before and after
- On the plate, the best pair of colours reads at 1.4:1: does not read.Falls short
- On screen, the text #2f2020 on the background #e2faf4 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
- The accent #c63a4c stands 4.6:1 from the background (a button needs 3:1) and as a link reaches 4.6:1 (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: #e2faf4 on 60% of the screen, #00aa95 on 30% (cards, bands, headers) and #c63a4c 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 1.4:1). That is why body text goes in #2f2020, a near-neutral ink tinted with the palette's hue: it is not in the book, and it is needed.
- The buttonThe accent #c63a4c stands 4.6:1 apart from the background: it works as a button, with text in #eef9f6.
- TemperatureWarm and cool together: let one lead and the other point. Here the background #00aa95 leads, and the accent #c63a4c is the first thing the eye will look for.
- 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.
- 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.
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 background isn’t pure black: it carries a little of the accent’s hue. That’s what separates a designed dark mode from one that looks like a fault.

}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 · green
Green is where the eye rests. Goethe says whoever looks at it neither wishes nor is able to imagine anything beyond it, which is why it was the colour for rooms you live in. In an interface that is precisely a background. § 802
- Accent and Heading · 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
What is happening to this palette
There are 10 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 reads on the circle
- Opposite #d84c5a · #00aa95
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
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.
