Op Art vs Psychedelic

オプ・アート / サイケデリック

Op Art comes from Geometric Abstraction and Psychedelic from Counterculture. Both are read here as style. They are reached for with some of the same intent, which is where they get confused.

KindStyleStyle
CuesHigh contrast / Repeated lines / Optical illusion / Geometric distortionSwirling curves / Complementary colors / Melting letters / Kaleidoscope patterns
Best used forKey visuals that stop the eye hard · Implying sound and motion in a stillDeepening immersion in music and experience · Festivity that escapes the everyday
TypeKeep a neutral sans away from the illusion zoneLettering that warps like liquid
CompositionDeform one repetition rule graduallyRadiate from the center; fill the margins
MaterialBlack and white plus exactly one colorSaturated color, waves, repeating pattern
CautionNever let the vibration reach the reading zone. Lower area and contrast on long-viewed screens.Hostile to long text and critical controls. Reserve places for the eye to rest.
