Three-Colour Concept Poster
A bold flat-colour conceptual poster in three inks — where every shape on the sheet is named with what it means, so nothing is there because the style has diagonals in it. Five fields.
We made two examples: a poster built around a listening head, and one about a harbour. In the harbour poster the sweeping arm is the breakwater, the upright form is the mooring and the black bars are ropes under tension; the bars pass behind the cleat and stop cleanly at its edges, so the layering holds. The figure on the breakwater gives the scale: without it, the green form would be a stripe rather than a sea wall.
Every shape has a meaning you can say out loud: the head is the listener, the column is the building, and the fine lines are the sound leaving. Nothing is there as filler: no decorative wedges, bars or dot grids. Check where shapes cross: here the ear is drawn on top of the column instead of behind it, so at that one point the layering flips.

Three-Colour Concept Poster
What this makes
A bold flat-colour conceptual poster in three inks — where every shape on the sheet is named with what it means, so nothing is there because the style has diagonals in it. Five fields.
The whole template, in one piece. The steps below are the entire workflow.
How to use it
- Copy the whole template with the button above.
- Replace the five FIELDS lines. Write the shapes field as shape, then dash, then meaning — if you cannot finish the sentence after the dash, that shape does not go in.
- Paste it into any image-capable agent or model, in one message. One run returns the poster.
- Point at each shape before shipping and say what it means. Anything you cannot name is the thing to delete.
What you swap
- The idea, in one sentence
- sound builds spaces you can stand inside
- The shapes, each with what it means
- a huge head in profile, cut off at the neck — the listener · a tall tapering column with an arch at its foot — the building · a bundle of fine curved lines running from the ear out to the right edge — the sound itself, leaving
- The inks
- cobalt blue, vermilion red, black — on warm cream stock
- The scale anchor
- one small standing figure in black at the foot of the column
- The type
- top left ARCHITECTURE OF SOUND · top right 2026 · down the left edge THE LISTENING ROOMS
Before it runs
- An idea you can say in one sentence. If you cannot, the shapes have nothing to be named against and the poster becomes decoration.
- Fewer shapes than you want. Three that mean something beat six where two are filler, and the filler is always the one you added last.
- Something to give scale. Abstract forms have no size until a person, a door or a chair tells you what they are.
When to reach for it
Culture programmes, festivals, lectures, exhibitions — anywhere a poster has to carry an idea rather than an offer. Templates in this style produce something genuinely handsome and then fill the gaps with slashing wedges that stand for nothing, which is the difference between a poster and a poster-shaped image.
What changes
- One conceptual poster on warm paper stock: three flat inks, big shapes, generous emptiness.
- Every shape declared with its meaning, so the composition can be read as a sentence rather than admired as an arrangement.
- A scale anchor that turns abstract forms into things of a size.
- Consistent occlusion — one stated front-to-back order, held everywhere the shapes cross.
- Type set small and quiet at the margins, letting the shapes do the talking.
Pairs with
- Transformation Metaphor PosterA quiet metaphor poster where one everyday thing turns into another — with the middle of the change actually drawn, instead of the two halves being cut and abutted. Five fields.
- 3D Character Screen BreakoutA soft-3D character coming out of a screen — with the crossing proved: named parts behind the plane, named parts through it, and the surface visibly giving way. Five fields.
- Bakery Food PosterA bakery-counter food poster — one dish shot large under a Didot title — with the overlap specified as a construction so the picture layers instead of stacking. Six fields.
