Do not recolor:
• TPU shell
• Outsole shell
• Traction elements
MASK 3 — SEMI-TRANSPARENT TPU SHELL ONLY
Modify only the TPU sidewall shell, TPU perimeter shell, TPU edgewall thickness regions, and visible TPU wall geometry.
Change TPU shell to: Lightly Dyed Semi-transparent ${foamOutsideColorId}
TPU
The TPU must remain Semi-transparent.
The coloration should exist naturally within the TPU material thickness.
The TPU must behave like premium Semi-transparent dyed urethane.
TPU SHELL CONSISTENCY
The Semi-transparent ${foamOutsideColorId} TPU shell must exhibit uniform dye concentration across all shell thickness regions.
Color intensity may vary only according to physical material thickness and optical depth.
Do not introduce:
• Random darker ${foamOutsideColorId} areas
• Uneven transparency
• Color streaking
• Patchy translucency
• Surface paint effects
• Local saturation fluctuations
Preserve exactly:
• Transparency level
• Refraction strength
• Internal reflections
• Optical depth
• Edge glow
• Thickness response
• Material density appearance
• Surface finish
Avoid:
• Opaque ${foamOutsideColorId} rubber
• Flat ${foamOutsideColorId} fills
• Frosted appearance
• Loss of transparency
The ${foamInsideColorId} midsole core must remain partially visible beneath the transparent ${foamOutsideColorId} TPU.
Use the example image, image 6, as an example on how the TPU should look like over the ${foamInsideColorId} inside.
Target result: tinted milky TPU, not transparent colored TPU.
MASK 4 — OUTSOLE TRACTION / GRIPPER ELEMENTS ONLY
Interpret every pixel within Mask 4 as traction geometry.
This includes:
• Bottom traction pods
• Gripper elements
• Outsole lugs
• Raised traction structures
• Side-visible traction elements
• Rear outsole teeth
• Edge traction geometry
• Molded grip structures
• Visible traction protrusions
Recolor all Mask 4 geometry to: ${soleColorId} Transparent Rubber / Translucent Urethane
The traction elements must remain translucent.
The ${soleColorId} coloration must appear naturally within the material thickness rather than as an opaque surface coating.
TRACTION SYSTEM CONSISTENCY
All traction elements must share identical translucent ${soleColorId} material properties.
Every traction pod, lug, hex cell, edge tooth, grip structure, and visible traction feature must exhibit:
• Consistent color density
• Consistent transparency
• Consistent subsurface scattering
• Consistent refractive behavior
• Consistent material appearance
Do not create:
• Mixed ${soleColorId} shades
• Orange contamination
• Uneven translucency
• Variable material interpretation
• Opaque regions
Preserve and enhance:
• Material transparency
• Optical depth
• Edge transmission
• Internal refraction
• Subsurface scattering
• Internal reflections
• Thickness-based color density
• Perimeter glow
• Material realism
Preserve exactly:
• Hexagonal traction definition
• Lug depth
• Raised grip structure
• Molded details
• Edge sharpness
• Contact shadows
• Physical realism
The traction system should appear manufactured from a single premium translucent ${soleColorId} performance rubber compound with factory-consistent pigmentation.
FINAL REQUIREMENT
Maintain identical material fidelity, texture fidelity, transparency fidelity, optical fidelity, lighting fidelity, and manufacturing realism to the source image.
The result must be visually indistinguishable from the original product photograph except for the specified material pigmentation changes.
Apply only the minimum localized color modifications required by the mask definitions.Second outsole angle, artwork transfer
Combines both generated intermediates: the edited fourth image supplies the outsole artwork and the edited fifth image supplies the base render.

Use the second image as the primary/base render and preserve it as closely as possible without redesigning the shoe.
Maintain the exact: camera angle, composition, lighting, materials, translucency, tread geometry, sole thickness, reflections, premium CGI product-render quality from the second image.
Transfer the outsole design and embedded logo from the first image onto the outsole of the shoe in the second image.
The outsole artwork in the first image is shown from a flat upward-facing view, while the second image shows the outsole from a rotated 3/4 underside perspective.
Re-orient the outsole artwork in object space before applying it to the second shoe.
The logo must be rotated to match the physical orientation of the shoe in the second image, not the orientation seen in the reference image.
The text must read naturally left-to-right from the visible viewing angle of the final render.
Do not: mirror the logo invert the typography reverse the text orientation transpose the outsole artwork directly from image-space
The logo orientation should follow the longitudinal axis of the shoe exactly as if it were originally manufactured into the outsole.
Preserve the logo’s relative placement within the outsole geometry (heel-to-midfoot positioning) while adapting it correctly to the perspective, curvature, and foreshortening of the second image.
The logo must: conform accurately to the sole curvature warp naturally with perspective appear embedded beneath the translucent rubber exhibit realistic depth and refraction remain partially diffused through the milky translucent sole material
Preserve the exact original logo coloration from the first image.
Do not introduce new hues, gradients, color variation, or artistic reinterpretation.
The logo should remain the same muted translucent gray/taupe appearance visible in the reference image.
Color fidelity is critical.
Transfer the outsole artwork exactly as shown in the source reference.
Preserve the translucent rubber appearance exactly as seen in the second image, including: subsurface scattering internal depth soft diffusion realistic refraction soft internal blur
Treat the outsole artwork as a physically molded internal outsole layer, not as a flat texture overlay.
Do not alter: shoe silhouette outsole shape tread structure sole translucency mesh upper render angle floating composition lighting setup
The final image should look as though the second render was originally manufactured with the outsole/logo design integrated into the sole from the beginning, with physically accurate orientation, perspective distortion, material embedding, optical behavior, and exact original monochrome coloration preserved from the source image.
