Format & Canvas
Vertical 9 :16. Background: {argument name="background color" default="warm off-white (# F4EFE6)"} or a neutral tone characteristic of the brand, with no visible shadows.
Background Pattern
Apply the brand’s signature motif as a large, tone-on-tone watermark (10–18% opacity). Motif size should be 15–25% of the canvas width, with a soft, slightly embossed feel.
Logo Placement
Position the Starbucks logo centered in the upper third. Width: 40–50% of the canvas. Use a flat, two-dimensional rendering in official brand colors.
Place the wordmark below the logo in spaced uppercase letters, matching the logo color. Wordmark height: approximately 60% of the logo height.
Product Placement
Photorealistic Starbucks frappuccino with full material fidelity (cup, lid, straw, textures, branding details).
Position: bottom right, angled at 25–35°. Cropped at 60–75%, occupying 55–65% of the canvas.
Use soft contact shadows (8–12% opacity), with no harsh shadows.
Lighting
Soft, directional daylight (5500–6000K). Key light from top left, fill from the right.
Minimal contrast (1.2–1.5:1), with global illumination for subtle light bounce.
No edge highlights; reflections only on metallic elements. Avoid hard shadows.
Typography & Finishing
At the bottom: a thin horizontal line (1 px, 80% width, in brand color).
Below it: microcopy ({argument name="microcopy text" default="social link or collection tag"}) in a clean sans-serif font, aligned with the context.
Technical Specifications
Photorealistic CGI (KeyShot/Octane style), 9: 16, ultra-high detail, f/16 depth of field, sharp edges, neutral color accuracy, slightly warm background, no environmental reflections.
