Neumorphism

Neumorphism (also known as “soft UI”) is a design trend that blends flat design and skeuomorphism by creating interfaces that mimic physical, tactile buttons and elements through soft shadows and highlights. Neumorphism often uses subtle, inset shadows to give a sense of depth and make buttons or cards appear to “pop” out of the background. While visually striking, neumorphism must be used carefully to ensure accessibility, as low contrast can hinder readability and usability.

Neumorphism became a popular design trend but has significant practical problems in real interfaces — the subtle shadows that create depth fail accessibility contrast requirements, and the all-same-hue aesthetic makes it difficult to distinguish interactive elements from decorative ones. It's most useful as an accent treatment for specific UI components (toggle switches, volume knobs) where the physical metaphor genuinely enhances the interaction, rather than as an interface-wide style.
