Use case: lighting-weather.
Asset type: surgical color correction of an existing clean website background plate.
Image 1 is the EDIT TARGET: runway-stage.png, 1680 x 936 pixels. Image 2 is COLOR REFERENCE ONLY: the approved runway website comp. Edit Image 1 only, retaining its exact 1680 x 936 dimensions and composition.

CHANGE ONLY THE PLUM BACKGROUND COLOR. The current plum is too bright and too saturated magenta, especially in the lower-left. Match the quieter, darker, less saturated brown-plum ground visible in Image 2. Reference ground samples from the approved comp are #441E33 at (10,10), #451D34 at (500,50), and #491F33 at (200,700) in the comp's 1505-pixel-wide coordinate system. On the target 1680x936 plate these correspond approximately to #441E33 near the top-left, #451D34 near x=558,y=56, and #491F33 near x=223,y=782. Treat those target hexadecimal colors as accurate paint swatches. Plum background should stay within the narrow, subdued dark brown-plum family approximately RGB 65-75 / 28-32 / 48-54. Avoid the current brighter values #501C39, #501E3A, and especially #662441. Eliminate the bright lower-left magenta glow completely. Preserve only very subtle, low-contrast studio tonal variation, with no visible magenta bloom and no extra lighting hotspot. This is a muted deep brown-plum, not purple, crimson, pink or black.

LOCK EVERYTHING ELSE. The peach platform is a protected region: preserve its material, color, fine stone texture, edge highlight, shape, curvature, thickness, perspective, silhouette, exact placement, and lighting UNCHANGED from Image 1. Do not recolor, move, regenerate, enlarge, shrink, crop, or reshape any part of the peach stage. Keep every stage boundary and edge at the same pixel position. Preserve the same framing and the same 1680 x 936 output dimensions. The only permitted visible change is the plum background becoming darker, browner, less saturated, and without a lower-left bright glow.

Final image must still contain ONLY the empty plum field and one peach stage. Do not copy or add anything from the website reference except its ground color. Absolutely no text, logos, letters, numbers, UI, phones, screens, people, objects, props, borders, watermarks, white sections, icons, shadows from nonexistent objects, or other additions.
