One Colour per Letter

Fat wobbly hand-drawn letters, two lines, every character flat-filled in one of three clashing brights, with a curved line of small type bending underneath. Four fields.

Summer reading

Two runs of the same template. A title with one colour per letter beside READ / WILD for a school summer reading challenge — same brights, same faint doodles behind, a different audience entirely.

Generated from this template with the fields shown above — the three brights cycle so no two neighbours match, every character carries its own darker outline and its own tilt, the curved line bends along the underside of the lower word, and the cursor doodles sit faint enough to miss. Run-to-run quirks: a few characters pick up extra flourishes the field did not ask for, and the cycle occasionally repeats a colour across the line break. The flat fills, the wobble and the pale ground hold every time.

One Colour per Letter

Produce ONE image: a playful hand-lettered poster. Follow every line below. Replace only the FIELDS block; everything after it is fixed.

First — do you have the fields?

If any field below still has braces around it, stop and ask. Put all the questions in one short message, and show the example under each one so they can see the shape of a useful answer. Wait for the replies, then draw. Never fill a brace yourself: a value you invented is a value nobody asked for, and it will look exactly as considered as the ones they did give you.

Ask in whatever language they are writing to you in. Translate the questions and the examples; do not make someone read English to tell you what they want.

The examples are only examples. If someone answers a question, use their answer; never fall back to the example because you prefer it.

If the fields are already filled in, ignore this and carry on.

Fields — replace these four lines only

  • The subject: {what this poster is for} e.g. Vibary's beginner workshop
  • The two lines: {an upper line and a lower line} e.g. upper line: MAKE IT — lower line: MOVE
  • The curved line beneath: {a short phrase, or two or three separated by dots} e.g. scrub it · paste it · ship it
  • The colours and the pattern: {three brights, a pale ground, and what the faint background doodles are} e.g. indigo, coral and lemon on a pale cream ground, with faint cursor and play-wedge doodles behind at very low opacity

The page

  • Square, 1:1. Centred and symmetrical.
  • Ground: a low-saturation pale colour — warm cream, pale mint, soft blue. Flat.
  • Behind everything, a faint hand-drawn pattern of small themed doodles in the same hand as the type, at roughly ten to fifteen percent opacity. It must be barely visible and must never compete with the title.
  • The title block occupies about sixty-five percent of the frame.

The title

  • Set in a fat, round, soft hand-drawn sans — chunky, friendly, clearly drawn rather than typed.
  • Every character is irregularly rounded, with a slight hand-drawn wobble to its outlines and a thin outline about one pixel wide in a darker shade of that character's own colour.
  • Split across two lines, upper and lower, with roomy spacing between characters.
  • Each character is nudged slightly out of alignment and tilted by a degree or two — different amounts for each. Nothing sits square or on a common baseline.
  • Every character is flat-filled with one of the three colours, cycled through the word. No two adjacent characters share a colour.
  • A few characters carry a tiny drawn detail suited to the subject — a dot, a small arc, a little peak, a snowflake, a sparkle.

The curved line

  • Below the title, a short line of the same handwriting, thinner and much smaller.
  • It bends along an arc that follows the underside of the title — never set straight.
  • Filled in one of the three brights, used consistently for the whole line.
  • Small round dots separate its parts.

Colour

  • The formula is: pale ground, three saturated brights, one of those three reused for the curved line. Nothing else.
  • The three should genuinely clash — orange with teal with yellow, pink with violet with blue, green with yellow with red.
  • Flat fills only. No gradient anywhere, no drop shadow, no soft shading, no texture. Depth comes entirely from flat colour meeting flat colour, plus the thin outlines.

Every part must

  • ✓ be drawn, not typed — visible hand irregularity everywhere
  • ✓ carry its own single flat colour with its own darker outline
  • ✓ sit off-square, tilted by its own amount
  • ✓ leave clean pale space around the title block
  • ✓ stay instantly readable

Never

  • ✕ gradients, shadows, glows, bevels or grain
  • ✕ a real font used straight, or a font with a wobble filter on it
  • ✕ two adjacent characters in the same colour
  • ✕ the curved line set straight
  • ✕ a background pattern strong enough to notice at a glance
  • ✕ text beyond the two lines and the curve

The result

A poster that looks like the shop owner drew it themselves and happened to be very good at it — flat, bright, cheerful, and cheap to print in a hurry.

The whole template, in one piece. The steps below are the entire workflow.

How to use it

  1. Copy the whole template with the button above.
  2. Replace the four FIELDS lines. Check your two lines are roughly the same width — that is what makes the block sit right.
  3. Paste it into any image-capable agent or model, in one message. One run returns the poster.
  4. Change only the colours and the faint pattern to move it season to season; the letterforms and the layout carry the brand.

Before it runs

  • A title that splits naturally into two lines. Forcing an odd break is the fastest way to lose the balance this layout depends on.
  • Exactly three brights that fight each other pleasantly. Two reads flat; four turns to confetti.
  • A short curved line. Long text will not bend without becoming unreadable.

When to reach for it

Shop openings, a season's promotion, a club poster, a workshop for kids. Everything is flat fills and one-pixel outlines, so it prints cheaply and reads across a street.

What changes

  • A finished square poster, centred and symmetrical, on a pale desaturated ground with a barely-there pattern behind it.
  • The title splits across two lines of round hand-drawn letters, each character nudged and tilted so nothing sits square.
  • Every character is flat-filled in one of three saturated clashing colours, cycled across the word, with a one-pixel darker outline of its own hue.
  • A small line of the same handwriting curves along the underside of the title, with dot separators between its parts.
  • No gradients, no shadows, no texture — depth comes only from flat colour against flat colour, which is what keeps it printable.
