プロンプト全文

¹Flat vector logo mark for a small-batch coffee roaster, centred on pure white. ²A single continuous line forms a coffee cherry that doubles as a sunrise arc, drawn at ³uniform 4-unit stroke weight with rounded caps, ⁴two colours only, deep terracotta and warm sand. ⁵Geometric construction on a visible circular grid, generous negative space, no gradients, no shading, no bevels, no 3D. Balanced at small sizes and ⁶legible as a single-colour stamp. Present the mark alone, with ⁷no lettering, no wordmark, no tagline, ⁸no mockup, no drop shadow, no watermark.

プロンプトの構造

以下の語句は、上のプロンプトにそのままの形で現れ、それぞれがひとつの要素を決めています。組み合わせを変え、置き換え、削りながら、自分用の版を作ってください。

01
Flat vector logo mark
Says both the style and the medium. Vector implies flat fills and clean edges even though the output is raster; it is the fastest way to suppress photographic lighting.
02
A single continuous line forms a coffee cherry that doubles as a sunrise arc
The concept, stated as a construction rule. A logo prompt without a construction rule produces decoration; with one, it produces a mark.
03
uniform 4-unit stroke weight with rounded caps
Stroke consistency is what makes a mark look drawn rather than sketched. Rounded caps read friendly; square caps read technical.
04
two colours only, deep terracotta and warm sand
Cap the palette explicitly. Left open, a mark drifts into four or five tints and stops working as a stamp.
05
Geometric construction on a visible circular grid
Shows the scaffolding in the image. Useful when you want to hand a direction to a designer rather than a finished asset.
06
legible as a single-colour stamp
The real test of any mark. Naming it pushes contrast and counter-shape decisions in the right direction.
07
no lettering, no wordmark, no tagline
Type is where generated logos fall apart. Ask for the symbol only and set the wordmark in a real typeface afterwards.
08
no mockup, no drop shadow, no watermark
Stops the model from presenting the mark on a business card or a coffee bag, which makes it unusable as a source file.

このプロンプトについての質問

Can it generate the company name too?

Ask it not to. Letterforms in generated images are unreliable at small sizes and in unusual weights. Generate the symbol, then set the name in a real typeface — the result is both better and editable.

How do I get several options in one style?

Keep every phrase and rewrite only the concept clause. Ten runs against ten concepts in one construction system gives you a coherent board; ten random prompts gives you noise.

Is a generated logo safe to use commercially?

Commercial use is allowed subject to our Terms of Service and applicable law, but a mark you intend to register still needs a clearance search and redrawing as real vector artwork.
