Impressionism thread, with Van Gogh's The Starry Night
Post by Impressions (@impression_ists), 2026-10-25
What it is, and who made it
A thread on the move from Impressionism to modern art; the images include The Starry Night.
Parts, layer by layer
- Sky: swirling strokes around stars and moon (O).
- Palette: #5f799b, #394f7d, #171c1f (M).
- Measures: spectral slope 1.69 (rough, mark-dense), wavelength 0.005 of width (stroke scale), edge softness 3.6 (M).
- Fluid reading: turbulence; additives wind and light; advection.
The framework behind it
Painted turbulence: eddies at several sizes drawn as strokes. Published analyses report that the painting's luminance has turbulence-like scaling (from memory, moderate confidence).
The same idea in distant fields
- Kolmogorov's energy cascade (big eddies feed small ones).
- Atmospheric eddies in satellite images.
- Marbled paper.
Dual edge
Van Gogh's sky is so familiar that imitation reads as pastiche; use the cascade, not the look.
