150-Shade Lighting Mockups

I’m putting together a demo for a new paint-brand site and need the “Lighting” section mocked up. The task is to take one hero room shot and render it in 150 pre-defined colors shades, then show each shade under four fixed presets—morning natural light, afternoon natural light, full shade, and warm artificial light. In final JPG/PNG frames (150 colours × 4 lighting scenarios) that I can drop straight into the front-end gallery.

My preference is a clean CGI/PBR workflow so the colour stays faithful across all lighting passes, but I’m open to whatever pipeline you normally use as long as the output looks photo-real and the hex/RGB values of the paints remain accurate. You’ll receive:

• The base room photograph (or you can stage a quick 3-D interior if that speeds things up).
• A spreadsheet with the 150 official colour codes and names.

Please let me know, in a short reply:
1. Your proposed approach (software, rendering method, and how you’ll handle bulk colour swaps).
2. The turnaround time for the first ten shades so I can sign off on the look, plus the full delivery timeline.
3. Your cost estimate, broken down if you prefer milestones.

Final deliverables: a neatly organised folder structure (Colour > Lighting Preset) and a brief note on any post-processing steps so my dev team can reproduce the effect later.

Looking forward to seeing your plan and getting this section live quickly.
