How to generate colorway variants of a garment from one photo

Turn a single product photo of a t-shirt, hoodie, dress, or jacket into 5–10 colorway variants without re-shooting — fabric texture, stitching, shadow detail and label artwork preserved. Edit with Paint masks the garment region and recolors only inside the mask, so the image's lighting, model, and background stay identical across the run. Standard workflow for a DTC brand launching a colorway expansion or a marketplace seller listing every available SKU.

What you need

  • One garment photo (flat-lay, on-mannequin, on-model — any input)
  • List of target colorways (hex codes are best; named colors work)
  • Apiway account on any tier (free covers ~3 variants)

Steps

  1. Open Edit with Paint and upload the source photo

    From the Creative hub, open Edit with Paint. Upload the single garment image you want to recolor. The source photo can be a flat-lay, packshot, ghost mannequin, or full on-model shot — colorway recoloring works on all of them.

    Open in Apiway

  2. Mask the garment region precisely

    Use the brush to paint over only the garment fabric — avoid model skin, background, hair, and any prints or label artwork you want to preserve. A clean mask is the single biggest predictor of output quality. Zoom in on collars, cuffs, and waistbands; sloppy edges are where unwanted recoloring leaks.

  3. Describe the target colorway in the prompt

    In the prompt field, describe the new color: 'forest green cotton', 'burgundy wool', 'pure white #FFFFFF cotton'. Hex codes work for brand-exact matching: 'navy blue #1B2A4E recolor, preserve fabric texture and stitching'. Keep the prompt short and specific — long prompts cause drift.

  4. Generate the first variant and inspect detail areas

    Run the generation. Inspect the output at 100% zoom: stitching lines, fabric weave, shadow gradients, label artwork. If any of those look smoothed-out or color-bled, the mask had a leak — tighten the mask edge and re-run.

  5. Duplicate the workflow for each colorway

    Re-open the source image, re-mask the garment (or save the mask as a brush preset on supported flows), and run for each target color. 8 colorways = 8 generations. The same model, same lighting, same pose across the run is what makes a colorway grid look like a real product line, not a series of disconnected shots.

  6. Export the set as a PDP / marketplace variant gallery

    Download all colorway outputs. On Shopify, attach them to the product's variant images so each color picker swatch loads its own image. On Amazon, use the parent-child relationship to wire each colorway as a variation under a single ASIN. On Etsy, add each colorway to the listing's image carousel.

Common mistakes

  • Sloppy mask edges leaking color into the model or background

    The single biggest quality killer. Always zoom in on collars, cuffs, hairlines, and the model–background boundary before generating. A 30-second mask cleanup beats five regenerations on a leaky mask.

  • Recoloring a garment with prints / artwork without a separate preserve-mask

    If the garment has a chest print, logo, or graphic you need to keep, exclude that area from the recolor mask explicitly. Otherwise the model recolors the print along with the fabric — the print becomes the same flat color as the new garment color and disappears.

  • Asking for an unrealistic color/material combination

    Prompts like 'metallic chrome cotton' or 'glow-in-the-dark wool' produce inconsistent output because real fabric doesn't behave that way. Stick to colors that exist in the garment's actual material space; describe sheen and material separately if you need them ('matte', 'glossy', 'brushed').

  • Generating for 20+ colorways in one batch and shipping without QA

    AI recoloring is high-quality but not 100% deterministic — every 8th–10th output drifts. Always eyeball the full set before publishing and regenerate the outliers. 5 minutes of QA saves a customer return for 'wrong color received'.

Troubleshooting

  • How many credits does an 8-colorway run cost?

    Roughly 60–120 credits at default settings. At 1 credit = $0.01 USD that's $0.60–$1.20 to recolor a single garment into 8 variants — vs. a $200–$1,500 product re-shoot for the same output. The free tier (100 one-time credits) covers ~6 variants; Starter ($10/month, 1,000 credits/mo) covers ~70 colorways at this cadence.

  • How does this preserve fabric texture better than a pure-AI recolor?

    Edit with Paint operates as a masked inpaint — only the masked region is regenerated, and the model is conditioned on the surrounding pixels including the existing fabric weave, shadow gradients, and stitching. Pure prompt-and-pray AI generates the entire image from text, which loses every detail signal the original photo carried. The hybrid pipeline keeps the photo as the anchor; the AI only changes color values inside the mask.

  • Can I recolor a garment but keep the chest print?

    Yes — mask the fabric region but explicitly exclude the print area from the mask. The print stays untouched (as part of the un-recolored region) while the surrounding fabric recolors. For complex artwork, a tighter, slower mask pays off more than a fast loose one.

  • Will Amazon accept colorway images that came from one source photo?

    Amazon's image policy is about content compliance (no overlays, true-white background for the main image, accurate product representation), not about how the image was captured. As long as the recolor matches what the buyer actually receives — which is the seller's responsibility — Amazon doesn't distinguish between re-shot and AI-recolored variant images.
