From Wada's dictionary, 1933
Wada combination 202
Its colours, with the book's names: Turquoise Green · Cobalt Green · Slate Color. The values are the book's; the roles and advice are ours.
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.
On a website
This is your colour 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.
Measured, before and after
On the plate, the best pair of colours reads at 10.9:1: AAA, reads with room to spare.
On screen, the text #212427 on the background #e9f9eb gives 14.3:1: AAA, reads with room to spare. APCA gives Lc 96: good for small text, the kind you read a paragraph of.
The accent #2e9f3c 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).
Under Protanopia, your accent and your background drop to 3.0:1. The button stops standing out: give it a border, change the lightness, or don't rely on colour alone to mark it.
How to use it
- Proportion
Distribute, don't equalise: #e9f9eb on 60% of the screen, #a4eeb2 on 30% (cards, bands, headers) and #2e9f3c 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.
- Text
Body text goes in #212427, 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 #1b3644, where size forgives.
- The button
The accent #2e9f3c stands 3.1:1 apart from the background: it works as a button, with text in #212427.
- Temperature
All cool: orderly and serious. So it doesn't feel distant, leave plenty of air and use the accent generously on whatever you want touched.
- How many
Three 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 dictionary
In 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 mixed-light ones: it already brings hierarchy. Keep it on screen: lightest at the back, darkest in front.
Goethe's reading
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.
The palette stays at rest: it neither advances nor recedes. Restful, but it points at nothing on its own.
- 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.
- 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.
- Same sector
Both fall in the same sector of the circle. There is no hue contrast, so whatever separates them will have to be lightness.
- With a neutral
A neutral with a colour that has no side on the circle. Goethe has nothing to say here.
- With a neutral
A neutral with a colour that has no side on the circle. Goethe has nothing to say here.
The kit for building it
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 same colour, at night.
The background isn't pure black: it carries a little of your hue. That's what separates a designed dark mode from one that looks like a fault.
