Combination 144 from Wada's dictionary · tone on tone, mixed light

Colour palette: Rosolanc Purple, Orange and Black.

One of the 348 combinations Sanzō Wada set down in 1933, with roles assigned, contrast checked and advice for using it.

From Wada's dictionary, 1933

Wada combination 144

Its colours, with the book's names: Rosolanc Purple · Orange · Black. The values are the book's; the roles and advice are ours.

The plate, as printed

3 colours in equal parts, as in the book. It is the inspiration, not the interface. Click one 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.

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.

And the footer, which nobody looks at until it looks wrong.
Aa

Measured, before and after

On the plate, the best pair of colours reads at 6.5:1: AA, it reads.

On screen, the text #f8ebe7 on the background #222222 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.

The accent #bf2ab6 stands 3.2:1 from the background (a button needs 3:1) and as a link reaches 4.6:1 (a word needs 4.5:1).

Under Protanopia, your accent and your background drop to 2.7:1. 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: #222222 on 60% of the screen, #000000 on 30% (cards, bands, headers) and #bf2ab6 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 #f8ebe7, 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 #ff5200, where size forgives.

  • The button

    The accent #bf2ab6 stands 3.2:1 apart from the background: it works as a button, with text in #f6f6f6.

  • Temperature

    All warm: close and unified, but to make something stand out don't rely on colour, rely on light: the important thing darker or lighter than its surroundings.

  • 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.

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.

  • Accent · violet

    The violet that would be intolerable as a background works in a border or a button. Same colour, different dose: this is a rule about surface, not about hue. § 790

  • Heading · orange

    Orange in a small patch is the accent that needs no explaining: it advances, it is seen, and it does not need size to do it. § 775

How each pair reads on the circle
  • Characteristic

    Orange and violet, with red skipped. It excites because it hints at pure red without ever showing it. § 822

  • With a neutral

    Next to black, a colour from the passive side loses. § 831

  • With a neutral

    Next to black, a colour from the active side gains energy. § 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.

The kit for building itNine tints, states, alerts and dark mode

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.

And in light

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.

From plate to screen

Six rules that are not ours.

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.

  1. Distribute 60 · 30 · 10

    One colour dominates, another accompanies and the third only points. In the book they sit in equal parts because that is how you compare them; on screen, equalising them is noise. Itten measured it in 1961: complementaries balance in areas inverse to their strength.

    Source: the 60-30-10 rule in interfaces (Hype4 Academy) and Itten's contrast of extension

  2. The background rests

    The background lives at one end of the lightness scale, very light or very dark, with little colour. Neither pure white nor pure black: tinted with the palette's hue, which is what separates a designed interface from an assembled one.

    Source: Refactoring UI, “Building your color palette”

  3. The book's colour lives on the surface

    Cards, bands and headers are the 30%: that is where Wada's colour shows at full size without carrying a paragraph. Material separates a colour from its role, “surface” and “on-surface”, so the hue can change without touching the interface.

    Source: Material Design 3, colour roles

  4. Paragraphs don't go in colour

    Long text goes in a near-black (or near-white) tinted with the palette's hue, at 7:1. The book's colours enter through headings, where size forgives. GOV.UK writes in #0b0c0c, not #000.

    Source: GOV.UK Design System and Refactoring UI

  5. The accent earns the button

    The most saturated colour goes only on what gets clicked, and is held to what the law asks of a component: 3:1 against the background (WCAG 1.4.11). As a word, 4.5:1 (1.4.3): a button and a link are not the same thing, and Radix gives them two different steps of its scale.

    Source: WCAG 2.2, criteria 1.4.3 and 1.4.11, and Radix Colors

  6. Move the lightness, not the hue

    Every adjustment is a change of lightness in a perceptual space (Lab, OKLCH): the hue stays put. In HSL, darkening a blue turns it violet and lightening it turns it lilac.

The colours

This combination also lives under a colour.

Where they come from

We read the book.

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.
