Thomas Gainsborough orchestrates warmth above all else - reds, ambers, and siennas take the lead. Muted throughout, the palette achieves its effects through value and temperature rather than chromatic force. #66372E functions as the palette's exclamation mark: highest chroma, lowest percentage (5.0%).
