Color = emotional pre-load
Before the viewer sees the product, the scene's dominant color sets the mood. Cool-blue scenes feel "trust, clean, premium." Warm-orange scenes feel "cozy, friendly, soft."

Don't shift the product color
When changing scene color, the product's own color must stay the same. A white cream entering a blue scene must not turn bluish. Lock this explicitly in the prompt.
