Glassmorphism vs Neumorphism

グラスモーフィズム / ニューモーフィズム

Both sit in UI Expression, so the question is not what they belong to but how they behave. Both are read here as style. They are reached for with some of the same intent, which is where they get confused.

Glassmorphism

Shows depth and hierarchy through translucent layers, floating information lightly.

Neumorphism

Makes background and controls one material, showing relief through soft shadow alone.

CautionLegibility breaks with the wrong background. Give text surfaces real opacity.Contrast failure comes easily. Mark key actions and states with color and outline too.
