I already hold two complete reference sets in PNG: one shows every colour on a single product size, the other shows every size in neutral grey. What I do not yet have is the full matrix—seven colours applied to each of my more-than-ten sizes. Your task is to merge those two references and output consistent, photo-realistic images for every possible colour-size combination. I’m open to any reliable workflow: Photoshop actions, Smart Objects, batch scripting, Python with Pillow or OpenCV, even Blender or another 3-D approach—as long as the output matches the lighting, shadows and texture of the provided PNGs. Deliverables • A complete set of high-resolution PNGs covering all sizes in all seven colours • The reusable script, action, or template you build, clearly documented so I can rerun it when new colours or sizes are introduced • A quick guide describing any folder structure or naming conventions required Acceptance criteria • Colours faithfully match the reference images (no tint shifts) • Product contours, shadows and highlights remain consistent across every image • File names follow the agreed colour_size pattern and pass a spot check on at least ten random combinations Send over a short outline of the technique you prefer and a sample of a similar batch job you have delivered, and we can get started right away.
