# HarborMug image prompt pack

Use the following four prompts as a coordinated visual set for US home-office shoppers. Keep the product matte blue and the settings warm white and pale oak. Generate no lettering; the designer should add banner copy afterward. These are finished prompts, not generated images or published assets.

The merchant facts and visual choices are synthetic; no real product reference image was supplied. Any generated product rendering will need merchant approval for physical accuracy before use.

## 1. Product hero

**Output:** 1:1 square, 1200 × 1200 px minimum recommended delivery. Primary listing image.

**Ready-to-use prompt**

Create a commercial studio product photograph of one HarborMug stainless-steel drinking vessel with a 500 ml capacity. It has a matte blue exterior, a straight cylindrical body, a gently rounded base, no handle, and no lid shown. Its supplied dimensions are 9 × 9 × 19 cm; preserve a tall, narrow silhouette approximately 19 cm high and 9 cm across. Place it upright in the center of a seamless warm-white background. Use a camera slightly above the rim at a restrained three-quarter view, revealing a small amount of the open top while keeping the body vertical and undistorted. Let the product fill about 78% of the square image height, with comfortable clear margins on every side and the entire base visible. Use a large diffused softbox from upper left with gentle front fill, a soft contact shadow beneath the base, and controlled highlights that preserve the matte finish. Keep the full product sharply focused, with believable stainless-steel material and a clean, unembellished surface. The palette is matte blue and warm white; the product is the sole subject. Deliver a square 1:1 composition.

**Exclusions:** No handle, lid, straw, accessories, packaging, extra vessels, logos, lettering, price badges, watermarks, glossy blue coating, warped rim, exaggerated perspective, floating base, steam, condensation, ice, cutaway insulation, or performance graphics. Do not add health, environmental, leakproof, or temperature-duration claims.

## 2. Lifestyle image

**Output:** 4:5 portrait, 1600 × 2000 px target delivery. Secondary listing or home-office editorial image.

**Ready-to-use prompt**

Create a natural editorial lifestyle photograph for US home-office shoppers, showing one matte blue stainless-steel HarborMug drinking vessel resting upright on a pale oak desk in a calm home office. The vessel has a 500 ml capacity and supplied dimensions of 9 × 9 × 19 cm: show a straight cylindrical body, gently rounded base, no handle, and no lid. Place it in the lower-right middle ground, fully visible, beside a closed unbranded notebook; include only a softly blurred edge of an unbranded laptop farther behind it to establish a working context. Keep the vessel visually dominant, occupying about 40% of the frame height, with realistic scale relative to the desk objects. Photograph from seated desk height with the camera just above the rim. Use soft directional window light from the left and a subtle bounce fill so the matte blue surface retains detail. Focus sharply on the vessel and let the background fall gently out of focus. Use navy blue, warm white walls, and pale oak, with restrained styling and a quiet, welcoming mood. Deliver a portrait 4:5 composition.

**Exclusions:** No people or hands, readable screens or notebook text, recognizable brands, additional drinkware, lid, handle, straw, clutter, dramatic color casts, wet desk, steam, condensation, ice, microwave, dishwasher, or visual claims about insulation, sustainability, health, or leak resistance. Do not imply that props are included with the product.

## 3. Store banner

**Output:** 3:1 landscape, 2400 × 800 px target delivery. Text-free background for a designer-composed store header.

**Ready-to-use prompt**

Create a wide commercial photographic store banner for HarborMug, aimed at US home-office shoppers. Show one matte blue stainless-steel drinking vessel standing on a pale oak surface against a warm-white wall. The vessel has a 500 ml capacity, supplied dimensions of 9 × 9 × 19 cm, a straight cylindrical body, a gently rounded base, no handle, and no lid shown. Position the whole vessel near 78% of the canvas width, with its center around 55% of the canvas height; let it occupy about 62% of the image height and keep its rim and base fully inside the frame. Use a nearly level camera with a slight view into the open top and no wide-angle distortion. Reserve the left 55% of the entire canvas as uninterrupted, low-detail warm-white negative space for text to be added later by a designer. Keep all product details and strong shadows on the right side; any pale oak surface visible on the left must remain visually quiet. Use soft window light from upper left, gentle fill, and a short subtle contact shadow on the right. Maintain a restrained navy-blue, warm-white, and pale-oak palette, with the vessel in crisp focus and the setting softly rendered. Deliver an exact 3:1 landscape composition with no text.

**Exclusions:** No generated store name, slogan, letters, symbols, logos, watermark, border, buttons, sale badge, text placeholder, extra vessels, handle, lid, straw, busy props, dark gradients behind the text area, or sharp shadows crossing the left 55%. No steam, condensation, or unsupported product claims.

**Designer handoff:** Add text only after image generation. Keep the text block within x = 5–50% and y = 20–80% of the full canvas. Preview the actual storefront crop before final placement; this master composition does not guarantee that the right-side product survives a centered mobile crop. If a narrow crop loses the product, prepare a separate crop from the approved master or a dedicated mobile composition.

## 4. Brand avatar

**Output:** 1:1 square, 1024 × 1024 px target delivery, suitable for a circular crop. Original brand concept for approval.

**Ready-to-use prompt**

Create an original minimalist brand avatar concept for HarborMug, a store serving US home-office shoppers. Draw one bold, simplified navy-blue silhouette of a tall, handleless cylindrical drinking vessel with a gently rounded base and a single broad warm-white opening near the top. Use flat geometric shapes with a clean vector-illustration aesthetic, smooth edges, and strong contrast on a solid warm-white background. Center the icon within the middle 65% of a square canvas so that a circular crop leaves generous clear space around it. Keep the silhouette upright, balanced, and recognizable at 32 pixels. Use only navy blue and warm white; there is no lighting, shading, photographic texture, or perspective effect in this flat icon. The concept should echo the product's tall proportions without acting as a technical product drawing. Deliver a square 1:1 composition with no lettering.

**Exclusions:** No wordmark, initials, fine text, handle, lid, straw, steam, waves, anchors, leaves, certification seals, recognizable third-party branding, stock-logo imitation, tiny details, gradients, shadows, metallic effects, border, watermark, or product-performance symbols. Do not present this concept as an existing approved logo.

## Production review and refinement

Use the hero as the first product-rendering candidate. Once the merchant approves its silhouette and blue color, use that approved image as a reference for the lifestyle and banner wherever the selected image tool supports references. Prompt text alone cannot guarantee matching geometry across separate generations.

Review every candidate for the straight cylindrical shape, rounded base, matte blue finish, plausible tall proportions, and absence of a handle or lid. Confirm the hero stays clear at thumbnail size, the lifestyle props do not compete with the product, the banner's left 55% stays empty, and the avatar remains recognizable in a 32 px circular preview. Capacity cannot be verified from an image; do not add visible capacity markings to imply verification.

If a candidate is mostly correct, edit it using a targeted instruction rather than starting over. For example: “Preserve the camera, lighting, background, and approved product silhouette. Remove the added lid and show the open top. Keep the exterior matte blue and change nothing else.” For a banner spacing issue: “Preserve the vessel and lighting. Move all product content to the right 45% and restore uninterrupted warm-white space across the left 55%. Add no text.”

Accept only after visual inspection of the generated files and confirmation of final pixel dimensions and aspect ratios. No images have been generated or visually approved as part of this prompts-only assignment. The supplied care instructions are hand-wash only and not microwave safe; imagery must not depict either prohibited care method. No health, environmental, leakproof, or temperature-duration guarantee is authorized.
