RAW image processing produces persistent color casts that are difficult to diagnose and correct

Photographers and image processing engineers struggle with yellow color casts appearing after RAW demosaicing and color correction, indicating a fundamental issue in their processing pipeline that current tools and documentation fail to adequately explain or solve. The problem is technically complex, requiring deep knowledge of Bayer pattern demosaicing, color space mathematics, and camera-specific calibration, yet existing solutions and tutorials don't provide clear debugging paths or pipeline validation methods.
