how to recolor images

I need to recolor a technical image depicting electrical cabinets and storage systems. Normally (until now), I've worked with Photoshop selections (also thanks to Lab Method ) and layers. I'd like to go faster by using the AI ​​models available in Adobe Firefly. Today I gave it a try, but the result wasn't what I expected: Gemini produced a well-colored image in some very complex areas (grills and container doors, which required some areas to be colored differently), while it blurred other areas.

I uploaded two images: the image to be edited (the image that needs to be recolored) and the image with the reference colors. I used this prompt:
Role & Reference Handling (CRITICAL): Act as an expert Industrial Product Designer and 3D Rendering Specialist. I have uploaded two reference images. You must clearly separate their roles:
Use Image 1 (Branded System) STRICTLY for the visual aesthetic, corporate color palette (Energy brand colors), material finishes, and overall brand identity.
Use Image 2 (New Unbranded System) STRICTLY for the absolute structural layout, physical proportions, geometric shapes, and composition (including the PCS cabinets, transformer cabinets, and support structure).
Task: Perform a precise style transfer and rebranding. Redesign the exact system shown in Image 2 by applying the corporate color palette, paint finishes, and branding aesthetic extracted from Image 1.
Constraints & Preservation (CRITICAL): Every single structural aspect, mechanical component, and the physical layout of Image 2 MUST remain exactly 1:1 unchanged. Do NOT add, remove, or alter any cabinets, support structures, or transformers. You are only applying a new "coat of paint" and brand identity over the existing geometry.
Style & Lighting: High-end commercial industrial photography. Clean, photorealistic rendering with professional studio lighting to highlight the new corporate colors and metallic textures. Clean, solid background.
Negative Constraints: Zero structural modifications to Image 2. No AI shape morphing, no alterations to the 3D layout, no AI artifacts, no messy backgrounds.

could someone suggest me how to proceed ?

p.s.: I didn't upload the images because I can't.
