Two movements, side by side
Pick any two eras and read them against each other: dates, what each was known for, defining traits, key artists and the palette the site uses for it.
What to look for between two eras
Start with what was rejected
The difference between two movements is usually easier to name as a refusal. Post-Impressionism refused Impressionism's dependence on the eye; Cubism refused the single viewpoint.
Then look at the light
Light is the fastest tell. Baroque light is theatre; Impressionist light is weather; Cubist light is even and flat, so the structure can be seen.
Then the surface
Smooth and invisible, or visibly painted? That single question separates more eras than the subject matter does.
Ignore the labels last
Nearly every painter here was called something they did not choose. The traits and the dates are the reliable part.
Short answers
Can I share a specific comparison?
Yes. The address bar updates as you change either side, so a copied link reopens the same pairing.
Why do the palettes look like bands?
Each band is one colour from the abstract palette khiar uses for that movement. It is a mood, not a photograph of a painting.
What is the most useful pair to start with?
Impressionism against Post-Impressionism. Same decade, same city, opposite ideas about what painting is for.
Put a painting next to the argument
The gallery shows which works belong to which movement, so you can test a comparison against real pictures.
