What this prompt does
This prompt generates a full logo variation system for a brand, not just one logo concept. You provide [brand_name], a [brand_description], the [brand_personality] traits, the [primary_color], and the [target_audience]. ChatGPT then describes a primary wordmark-plus-icon logo, an icon-only logomark, a monogram, horizontal and vertical lockups, color variations, responsive rules, and usage guidelines.
The variables steer the design direction. [brand_symbolism] tells the model what the icon concept should represent, [min_size] sets the smallest size the logomark must stay legible at, and [brand_initials] define the monogram. [color_variation_count] controls how many color treatments it generates (full color on light and dark, single-color, grayscale). Because this is a text-to-image style prompt, the model returns detailed visual descriptions and specifications rather than rendered files — it is designed to brief a designer or a separate image generator on exactly what to produce.
When to use it
- You need a complete logo system with wordmark, icon, monogram, and lockups, not a single file.
- You are building a product and want logo variations ready for headers, favicons, and app icons.
- You want responsive logo rules defining when to switch from full logo to icon-only.
- You need usage guidelines covering clear space, minimum size, and forbidden treatments.
- You are briefing a designer or an image-generation tool and want a precise specification.
- You want consistent color variations for light, dark, single-color, and print contexts.
Example output
The output is a structured logo specification. It describes the primary logo's icon concept tied to [brand_symbolism] plus the font style and spatial relationship, an icon-only logomark that holds up at [min_size], a monogram using [brand_initials] that reads at 16x16 pixels, horizontal and vertical lockups with proportions, [color_variation_count] color treatments, responsive switching rules with breakpoints and hover behavior, and a usage-guidelines block covering clear space in icon-height units and forbidden treatments. You then hand it to a designer or image model to render.
Pro tips
- Make
[brand_symbolism]concrete — "flowing connections between nodes" gives the icon concept direction that "modern and clean" never will. - Set
[min_size]to the real smallest context you need, like a favicon, so the logomark is designed to survive it. - Provide
[brand_personality]traits that genuinely conflict where useful (approachable yet efficient) to get a more distinctive concept. - Specify
[primary_color]as a hex value so the color-variation section is precise rather than vague. - Remember the output is a description, not artwork — feed it into an image generator or a designer to actually produce the logo.
- Iterate on the icon concept first; once you like that, re-run for lockups and color variations so the system stays coherent.
- Describe
[target_audience]honestly, since a logo aimed at design agencies should read differently from one aimed at enterprise buyers, and the model leans on that to set tone. - Use the responsive rules it generates as a real engineering reference: the breakpoint at which you swap the full logo for the icon-only mark belongs in your header component, not just a brand deck.
