Aero (#7CB9E8) is a mid-tone cool shade that appears across 4 master palettes in our corpus, most prominently in the work of Alexandre Thomas Francia, Louis Marcoussis, and Antonio Jacobsen and the Romanticism tradition. Master painters paired it most often with Gold Fusion (#85754E), Seal brown (#59260B), and Jonquil (#F4CA16). The combination forms a steady, atmospheric chord, built on a complementary hue split, leans on warm companions to lift a cool source color, with a moderate step down in value that keeps the source forward.
