From Wada's dictionary, 1933
Wada combination 245
Its colours, with the book's names: Carmine Red · Oil Green · Dark Tyrian Blue · 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 4.9:1: AA, it reads.
On screen, the text #ecefe6 on the background #1c212f gives 13.8:1: AAA, reads with room to spare. APCA gives Lc 94: good for small text, the kind you read a paragraph of.
The accent #c63846 stands 3.1:1 from the background (a button needs 3:1) and as a link reaches 4.7:1 (a word needs 4.5:1).
Under Protanopia, your accent and your background drop to 2.3:1. 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: #1c212f on 60% of the screen, #0d2b52 on 30% (cards, bands, headers) and #c63846 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 #ecefe6, 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 #6ea900, where size forgives.
- The button
The accent #c63846 stands 3.1:1 apart from the background: it works as a button, with text in #f4f6fe.
- Temperature
Warm and cool together: let one lead and the other point. Here the background #0d2b52 leads, and the accent #c63846 is the first thing the eye will look for.
- How many
Four colours demand discipline: #0d2b52 and #ecefe6 are the base, the other two are detail. If in doubt, drop the support colour before the accent.
- In the dictionary
In 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 dark ones: it needs light text and large surfaces; in small pieces it clogs.
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 crosses both sides of the circle, active and passive. It carries the most tension and most needs one of the two to lead.
- Surface · blue
Blue recedes: it draws the eye inward rather than coming out to meet it. It holds a large surface without fighting whatever sits on top.
- 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.
- Heading · 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.
- Opposite
Opposite on the circle: together they complete what the eye asks for on its own. It is the only category Goethe approves without reservation.
- Characteristic
Blue and red, with violet skipped. It approaches the effect of the violet their mixture would produce.
- With a neutral
Next to black, a colour from the active side gains energy.
- Adjacent
Adjacent on the circle. This is the one pair Goethe dismisses outright, and that judgement does not hold today — teal is well liked. What does hold is the measurable half: two neighbours with no difference in lightness produce no contrast.
- With a neutral
A neutral with a colour that has no side on the circle. Goethe has nothing to say here.
- With a neutral
Next to black, a colour from the passive side loses.
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, by day.
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.
