Color you can hear.

Pick a chord, get a palette. Every advertising idea in this gallery starts from a musical chord — its notes translated into color by PCS-1.0, a pitch-to-color mapping. Complementary color itself is centuries old; what’s new here is the bridge: a musical tritone and a complementary pair are the same relationship, so a chord you can play becomes a palette you can brief.

1 · Hear it

A chord is three or four notes that belong together — B minor sounds moody and premium before you ever see a color.

2 · See it

PCS-1.0 gives every pitch one fixed color. The chord’s notes become the palette — no guessing, no mood-board roulette.

3 · Sell with it

Each palette below is shown in real scenes — a taco stand, a diner, a perfume bottle — and on real products and brand marks, at both the light end and the dark end of its range.

PCS-1.0 — The twelve tones

Minor · The noir chordB minor

B #AAFF00 D #008FFF F♯ #A80000

Electric yellow-green, deep blue, blood red. In music B minor broods; in color it glows in the rain — the blue does the atmosphere, the red gives it danger, and the yellow-green only needs a reflection to steal the frame.

Best for

  • Film, streaming & entertainment key art
  • Fashion and streetwear with an edge
  • Watches, instruments, nightlife, spirits
  • Any brand that wants mystery over cheer

The angle

Lead with blue, threaten with red, let yellow-green appear only as light — a lamp, a reflection, a lining. Restraint is what makes it feel expensive instead of loud. At the light end it turns summery and strange; at the dark end it’s pure noir.

Minor · The romantic chordD minor

D #008FFF F #820097 A #FF7800

Ocean blue, deep violet, ember orange. D minor is the saddest of keys in the old lore — and the most romantic palette here: cool blue and violet hold back while orange burns in the middle, like a coal in a perfume bottle.

Best for

  • Fragrance, beauty & luxury goods
  • Travel, hotels, airlines with soul
  • Classical music, wine & evening brands
  • Anything sold at dusk

The angle

Let A-orange be the single warm thing — a bottle, a sunset, a cocktail glow — inside a blue-violet world. One warm object in a cool scene is the oldest attention trick there is, and D minor gives it to you by construction.

Cut from this gallery at Jeff’s call: the glowing-headphones ad — “kind of cheesy.” Realism and restraint are house rules here.

Minor · The street chordG minor

G #D80000 B♭ #FFEF00 D #008FFF

Signal red, taxi yellow, true blue — the primaries, with a minor ache underneath. G minor is the most everyday palette in the gallery: it’s already on your street, which is exactly why it converts. Nobody has to imagine it.

Best for

  • Fast food, diners & casual chains
  • City services, transit, delivery
  • Coffee, music venues, local retail
  • Brands that need instant, friendly recognition

The angle

Don’t invent props — find the palette where it already lives. A red awning, yellow umbrellas, a blue tile counter. When the scene could be photographed on a real block, the chord stops being a concept and becomes recognition.

Also cut at Jeff’s call: an all-yellow sneaker ad and an all-red motorcycle — “no one has” those. If a product couldn’t exist, it doesn’t run.

Minor · The first chordA minor

A #FF7800 C #3AFF00 E #7900EA

Ember orange, vivid green, violet. A minor is the first chord most guitarists ever learn — plain-spoken, no sharps, no flats — and its palette is just as direct: the orange of ripe produce and amber drinks, green doing the growing, violet arriving as eggplant, dusk, and velvet shadow.

Best for

  • Grocery, farmers markets & farm-to-table brands
  • Hotels, lounges & evening hospitality
  • Garden, grocery-delivery & natural food brands
  • Anything honest, earthy, and warm

The angle

Play the orange against the green and let violet be the depth — a cabbage, a shadow, a dusk sky. At the light end it’s a market morning; at the dark end, the same grocery list becomes a cocktail lounge. Few palettes travel further on one chord.

Minor · The folk chordE minor

E #7900EA G #D80000 B #AAFF00

Violet, signal red, yellow-green. E minor is the open-string folk chord — campfires, gardens, songs everybody knows — and its palette lives outdoors: red arriving as a rose or a geranium rather than a logo, yellow-green as foliage, violet as the light at the end of the day.

Best for

  • Florists, garden centers & nurseries
  • Weddings & outdoor entertaining
  • Garden restaurants & countryside hospitality
  • Natural, handmade & heritage brands

The angle

Don’t paint anything — plant it. E minor is the rare palette a florist already stocks and a garden already grows. Shoot it at two hours of the same day and you get both ends of the range for free.

Minor · The theatrical chordC minor

C #3AFF00 E♭ #1000FF G #D80000

Green, deep indigo, signal red. C minor is the most theatrical of the minors — Beethoven’s key — and its palette behaves like stage design: a saturated indigo that reads as a painted door by day and shadow by night, red in the awning and the leather, green in the shutters and the basil.

Best for

  • Cafés, bistros & Mediterranean restaurants
  • Travel & old-town hospitality
  • Wine, opera & winter brands
  • Any brand with an old-world address

The angle

Architecture carries this one: paint the door indigo, hang the red awning, pot the green. C minor rewards places over products — shoot a real street corner and the chord is already there, waiting for a table.

Minor · The passionate chordF minor

F #820097 A♭ #FF2000 C #3AFF00

Deep violet, scarlet, vivid green. F minor is the heavy one — four flats, all passion — and its palette is a flower market at noon and a jazz singer at midnight: scarlet doing the feeling, violet doing the depth, green keeping both honest.

Best for

  • Florists & flower markets
  • Jazz clubs, cabaret & live music
  • Spirits & dramatic retail
  • Brands that lead with feeling

The angle

Let scarlet be a person or a flower, never a background. F minor’s drama comes from one hot note against violet depth — a dress, a poppy, a stage light — with green as the stems and shadows that make it believable.

Major · The everyman chordC major

C #3AFF00 E #7900EA G #D80000

Green, violet, red — the same three notes as C minor with the middle one lifted, and the mood lifts with it. C major is the plainest chord in music and its palette is just as plain-spoken: tomatoes, lavender, leaves. Lunch outside, then dinner on the same terrace.

Best for

  • Family restaurants & garden dining
  • Food brands, olive oil & wine
  • Home, garden & outdoor living
  • Friendly, unpretentious everything

The angle

C major vs. C minor is the cleanest demo in this gallery: swap indigo for violet, keep the red and green, and theater becomes lunch. Use the pair to show a client exactly what one note does to a brand’s mood.

Major · The campfire chordG major

G #D80000 B #AAFF00 D #008FFF

Signal red, yellow-green, true blue — G minor’s palette with the ache removed. G major is the campfire and road-trip chord, and its colors are the colors of being outside: a red umbrella or a red pickup, lime-bright gear, and all that blue sky doing the heavy lifting.

Best for

  • Beach, outdoor & recreation brands
  • Road trips, trucks & Americana
  • Folk, country & feel-good retail
  • Tourism that smells like sunscreen

The angle

Compare it with G minor on this page: identical notes except one, and the street becomes a holiday. G major is the daylight setting of the same dial — schedule it for anything sold between May and September.

Major · The heartland chordD major

D #008FFF F♯ #A80000 A #FF7800

True blue, deep red, ember orange. D major shares its notes with D minor but swaps violet for deep red — and turns romance into backbone. It’s the heartland palette: barn red, pumpkin orange, big-sky blue, with a working harbor waiting at the dark end.

Best for

  • Farm, harvest & rural brands
  • Sport, trucks & Americana
  • Coastal & working-waterfront tourism
  • Anything honest and built by hand

The angle

Blue does the sky, orange does the harvest, red does the barn and the boat hull. D major is D minor’s daylight sibling — put the two sections side by side in a pitch and the client will feel the difference before you explain it.

Major · The loudest chordA major

A #FF7800 C♯ #00FFEC E #7900EA

Ember orange, electric cyan, violet. A major is the extrovert of the majors — tropical water, citrus, bougainvillea — a palette that reads as a resort before a single word of copy. At dusk it turns into neon-era Miami: a turquoise hotel against a violet sky.

Best for

  • Resorts, pools & tropical travel
  • Tech, gaming & youth brands
  • Beverages & summer launches
  • Anything that must be seen from the highway

The angle

Cyan is the rarest note in natural scenes, which is why A major feels designed even when it isn’t — pool water and Deco stucco supply it honestly. Spend the orange on the furniture and the people, and let violet arrive with the evening.

Major · The celebration chordE major

E #7900EA G♯ #FF2000 B #AAFF00

Violet, scarlet, yellow-green — E minor’s exact palette with the middle note raised, and the garden party replaces the dusk. E major is festive without confetti: roses and geraniums doing the scarlet, petunias the violet, and a lime twist waiting in the evening cocktail.

Best for

  • Garden parties & celebrations
  • Cocktails, aperitifs & entertaining
  • Florists & spring/summer retail
  • Joyful brands that stay tasteful

The angle

Side-by-side with E minor, this is the other great one-note demo: same garden, happier chord. E major suits brands that celebrate in daylight and toast at dusk — never the reverse.

Major · The pastoral chordF major

F #820097 A #FF7800 C #3AFF00

Deep violet, ember orange, vivid green. F major is the pastoral key — the countryside chord — and it swaps F minor’s scarlet passion for orange warmth: a farmhouse kitchen in the morning, and at the dark end, a huge low sun over violet ranges.

Best for

  • Farmhouse, kitchen & home brands
  • Landscapes, national parks & rural travel
  • Food with a countryside story
  • Calm, grounded, honest products

The angle

Violet is F major’s surprise: it hides in shadows, distant hills, and dusk, so the orange and green can feel like pure daylight. Let it arrive late in the frame — the ranges at the horizon, the shade under the table.

Dominant 7 · The blues chordC7

C #3AFF00 E #7900EA G #D80000 B♭ #FFEF00

C major plus one restless note — B♭ yellow — and the palette gets its appetite. Four colors: green, violet, red, and the yellow of stage lights and taxicabs. C7 is the sound of a bar band starting up, and it photographs like one: street café by day, blues club by night.

Best for

  • Bars, blues & live-music venues
  • Burgers, diners & hungry brands
  • Street cafés & city life
  • Entertainment with grit

The angle

The fourth note is the lesson: a seventh chord’s extra color is what separates a palette from a poster. Give the yellow one job — a taxi, a stage light, a booth lamp — and let the C-major trio hold the room around it.

Major 7 · The quiet-luxury chordCmaj7

C #3AFF00 E #7900EA G #D80000 B #AAFF00

C major softened by B’s yellow-green — where C7’s fourth note shouts, Cmaj7’s whispers. Four close tones for calm, expensive spaces: orchids on a hotel terrace by day, a chartreuse cocktail beside a piano at night. The subtlest palette in the gallery, and the priciest-feeling.

Best for

  • Boutique hotels & resorts
  • Skincare, spa & quiet luxury
  • Jazz lounges & piano bars
  • Brands that lower their voice

The angle

Keep the fourth color barely there — pale foliage, a champagne glint, one chartreuse drink. Cmaj7 teaches the gallery’s most valuable lesson: the difference between loud luxury and quiet luxury is a single note, played softly.

Diminished · The held breathC diminished

C #3AFF00 E♭ #1000FF F♯ #A80000

Green, indigo, deep red — three notes stacked in perfect, nervous symmetry. Diminished is the raised eyebrow of music, and its palette works the same way: a storm coast under bruised indigo cloud, a candlelit cellar where the green is bottle glass. Tension, sold honestly.

Best for

  • Wine cellars & dramatic dining
  • Mystery, horror & thriller launches
  • Storm-coast & rugged travel
  • Halloween and limited editions

The angle

Use it rarely and mean it. Diminished can’t carry an everyday brand — it’s the palette of warnings, secrets and weather. Even its “light” example is an overcast coast: with this chord, light end is a relative term.

Augmented · The floating chordC augmented

C #3AFF00 E #7900EA A♭ #FF2000

Green, violet, scarlet — perfectly symmetrical, pleasantly unreal. An augmented chord never quite lands, and its palette floats the same way: balloons at dawn, an aperitif above a violet city. Wonder instead of certainty, for brands selling the future.

Best for

  • Tech launches & futurist brands
  • Festivals, events & celebrations
  • Rooftop bars & destination marketing
  • Anything dreamlike, on purpose

The angle

Augmented is the specialist: deploy it when the product itself feels slightly impossible — a launch, a reveal, a first flight. The symmetry does the uncanny work; keep the scene itself real so the wonder stays believable.

Try a chord
