Claymorphism

What you see

The perceptual fingerprint, in the order you notice it.

• Very large radii making every element read as a rounded lump
• A soft inner highlight along the top inside edge
• Coloured, not grey, drop shadows tinted by the element's own fill
• Matte pastel fills with no gloss or specular highlight
• Elements that overlap and stack like physical objects

Best for

• Consumer, education and community products with a friendly voice
• Onboarding, empty states and marketing pages that need warmth
• Brands with pastel or mid-saturation palettes

Avoid when

• The product is serious, professional or high-stakes
• The interface is dense — the radii and shadows eat enormous space
• The kit is monochrome or very dark; clay needs colour to tint its shadows

Accessibility

Where this style tends to fail an audit, and what fixes it.

• Pastel fills with light text is the standard failure. Text on a clay surface must clear 4.5:1 against the actual fill, which usually means dark text on pastel.
• Enormous radii shrink the usable content box — check that labels do not collide with the corner curve at small sizes.
• The inner highlight is decorative; the element still needs a boundary that survives it, since clay shapes often sit on similarly tinted backgrounds.
