🔴 채택한 변경 없음. 두 후보를 인게임 Play 로 재고 «수치가 좋아져도 그림이 나빠져서» 기각했다.

① ShadowsMidtonesHighlights.shadows (0.78,0.58,1.25) → G 0.75/0.85/0.95 · B 1.10/1.00 · 거의 중성
   보정 재탐색 후 화면 dHue 14.1° → 13.9~14.8° = **이득 0**.
   배경은 바위·그림자의 보라 회색이 옅어져 PD 승인 룩이 무너진다(e_final_wide.png 오른쪽).
   → 3차에서 「이 값이 진범」이라 본 판단은 방향은 맞았으나, 고쳐도 캐릭터 색이 개선되지 않는다.

② 부위 그룹별 _DiffuseColor (Skin 0.88,1.10,0.80 / M05 1.04,0.972,1.04 / Hair 0.965,1.025,0.965)
   유채 가중 dHue 17.0° → 10.7° · 머리 피부 -40.9° → +3.3° (수치는 합격선에 근접)
   그러나 **피부·머리칼이 초록으로 뜬다**(e_final_close.png 가운데).
   원인 = 목표색(피부 알베도 평균 (240,217,152) · Hue 43°)이 노란 크림이라
   화면을 그 색상으로 끌면 살색이 아니라 황록으로 보인다 → **지표 자체가 피부에는 부적합**.

유지 = 3차 상태(중성 앰비언트 + 전역 _DiffuseColor (0.993,1.028,0.874)) — 세 안 중 육안 최선.
