Claymorphism

> "Like interacting with a pristine, digital claymation set. Soft, bubbly, and incredibly approachable."

When to Use

Use this sub-style when the user's request matches the aesthetic described above. This is a child reference of the design-it skill and is not meant to be triggered directly.

Core Principles

1. Fluffy 3D Volume: Elements look like inflated balloons or soft clay blocks.
2. Double Inner Shadows: The signature of claymorphism is an inset light shadow on the top-left and an inset dark shadow on the bottom-right, giving 3D volume to a solid shape.
3. Continuous Curves: Maximum border-radius. No sharp edges exist in this universe.

Visual DNA

• Colors: Thrives on pastels and bright, friendly hues. Desert Mirage, Earth-Grounded Elegance, or custom pastel palettes work best.
• Typography: Playful, thick, rounded fonts (e.g., Sniglet, Fredoka One, Nunito).
• Shapes: 'Squicles' (squares with heavily rounded, continuous corners) and perfect circles.

Web Implementation

• Distinct from Neumorphism: Claymorphism elements detach from the background (they have drop shadows) and use inner shadows to create volume, often using colors that contrast with the background.
• CSS Example:

css
.clay-card {
  background-color: #F8B4A6; /* Soft coral */
  border-radius: 32px;
  padding: 40px;
  
  /* 
    1. Outer drop shadow (detaches from background)
    2. Inner top-left highlight (volume)
    3. Inner bottom-right shadow (volume)
  */
  box-shadow: 
    8px 8px 24px rgba(0, 0, 0, 0.15),           /* Outer */
    inset -8px -8px 16px rgba(0, 0, 0, 0.1),    /* Inner dark */
    inset 8px 8px 16px rgba(255, 255, 255, 0.4); /* Inner light */
    
  transition: transform 0.2s cubic-bezier(0.34, 1.56, 0.64, 1); /* Bouncy */
}

.clay-card:hover {
  transform: translateY(-5px) scale(1.02);
}

App Implementation

SwiftUI

swift
struct ClayCard: View {
    @State private var isPressed = false
    
    var body: some View {
        VStack(spacing: 16) {
            Image(systemName: "cloud.sun.fill")
                .font(.system(size: 48))
                .foregroundColor(.white)
            Text("Claymorphic Card")
                .font(.system(size: 20, weight: .bold, design: .rounded))
                .foregroundColor(.white)
        }
        .padding(40)
        .background(Color(red: 0.97, green: 0.71, blue: 0.65)) // Soft coral
        .cornerRadius(32)
        // Outer shadow — detaches from background
        .shadow(color: .black.opacity(0.15), radius: 12, x: 8, y: 8)
        // Inner highlight (top-left) — faked with overlay
        .overlay(
            RoundedRectangle(cornerRadius: 32)
                .stroke(
                    LinearGradient(
                        colors: [.white.opacity(0.5), .clear, .black.opacity(0.1)],
                        startPoint: .topLeading,
                        endPoint: .bottomTrailing
                    ),
                    lineWidth: 3
                )
        )
        // Bouncy spring animation on tap
        .scaleEffect(isPressed ? 0.95 : 1.0)
        .animation(.interpolatingSpring(stiffness: 300, damping: 10), value: isPressed)
        .onTapGesture { }
        .simultaneousGesture(
            DragGesture(minimumDistance: 0)
                .onChanged { _ in isPressed = true }
                .onEnded { _ in isPressed = false }
        )
    }
}

• The "clay" volume comes from a gradient stroke overlay: white on top-left, dark on bottom-right.
• Use .interpolatingSpring(stiffness: 300, damping: 10) for the bouncy feel — critical for clay aesthetics.
• Background color should be pastel/bright but NOT the same as the parent (unlike neumorphism).

Flutter

dart
class ClayCard extends StatefulWidget {
  @override
  State<ClayCard> createState() => _ClayCardState();
}

class _ClayCardState extends State<ClayCard> with SingleTickerProviderStateMixin {
  double _scale = 1.0;

  @override
  Widget build(BuildContext context) {
    return GestureDetector(
      onTapDown: (_) => setState(() => _scale = 0.95),
      onTapUp: (_) => setState(() => _scale = 1.0),
      onTapCancel: () => setState(() => _scale = 1.0),
      child: AnimatedScale(
        scale: _scale,
        duration: const Duration(milliseconds: 200),
        curve: Curves.elasticOut,  // Bouncy clay feel
        child: Container(
          padding: const EdgeInsets.all(40),
          decoration: BoxDecoration(
            color: const Color(0xFFF8B4A6), // Soft coral
            borderRadius: BorderRadius.circular(32),
            boxShadow: [
              // Outer shadow
              BoxShadow(
                color: Colors.black.withOpacity(0.15),
                offset: const Offset(8, 8),
                blurRadius: 24,
              ),
            ],
            // Gradient border for the clay volume effect
            border: GradientBorder(
              gradient: LinearGradient(
                colors: [
                  Colors.white.withOpacity(0.5),
                  Colors.transparent,
                  Colors.black.withOpacity(0.1),
                ],
                begin: Alignment.topLeft,
                end: Alignment.bottomRight,
              ),
              width: 3,
            ),
          ),
          child: Column(
            mainAxisSize: MainAxisSize.min,
            children: [
              const Icon(Icons.wb_sunny, size: 48, color: Colors.white),
              const SizedBox(height: 16),
              const Text('Claymorphic Card',
                style: TextStyle(fontSize: 20, fontWeight: FontWeight.bold,
                  color: Colors.white)),
            ],
          ),
        ),
      ),
    );
  }
}

• Use Curves.elasticOut or Curves.bounceOut for the spring animation — essential for the clay feeling.
• Gradient borders require a custom ShapeDecoration or a Stack with a gradient container behind the main container.
• Alternative for inner shadow: use flutter_inset_box_shadow package with light top-left and dark bottom-right insets.

React Native

jsx
const ClayCard = () => {
  const scale = useRef(new Animated.Value(1)).current;
  
  const pressIn = () => {
    Animated.spring(scale, {
      toValue: 0.95,
      friction: 3,      // Low friction = bouncy
      tension: 100,
      useNativeDriver: true,
    }).start();
  };
  
  const pressOut = () => {
    Animated.spring(scale, {
      toValue: 1,
      friction: 3,
      tension: 100,
      useNativeDriver: true,
    }).start();
  };

  return (
    <Pressable onPressIn={pressIn} onPressOut={pressOut}>
      <Animated.View style={{
        transform: [{ scale }],
        padding: 40,
        backgroundColor: '#F8B4A6',
        borderRadius: 32,
        alignItems: 'center',
        // Outer shadow
        shadowColor: '#000',
        shadowOffset: { width: 8, height: 8 },
        shadowOpacity: 0.15,
        shadowRadius: 12,
        elevation: 8,
        // Gradient border must be faked with a wrapper or SVG
        borderWidth: 3,
        borderColor: 'rgba(255,255,255,0.3)', // Simplified — top highlight
      }}>
        <Text style={{ fontSize: 48 }}>☀️</Text>
        <Text style={{
          fontSize: 20, fontWeight: '700', color: '#FFF', marginTop: 16,
        }}>
          Claymorphic Card
        </Text>
      </Animated.View>
    </Pressable>
  );
};

• Use Animated.spring with low friction (3-5) for the signature bouncy clay behavior.
• Gradient borders aren't possible natively — use a solid white-tinted border as a simplified approximation, or wrap in an expo-linear-gradient View.

Jetpack Compose

kotlin
@Composable
fun ClayCard() {
    var isPressed by remember { mutableStateOf(false) }
    val scale by animateFloatAsState(
        targetValue = if (isPressed) 0.95f else 1f,
        animationSpec = spring(dampingRatio = 0.3f, stiffness = 300f),
    )
    
    Box(
        modifier = Modifier
            .graphicsLayer { scaleX = scale; scaleY = scale }
            .shadow(8.dp, RoundedCornerShape(32.dp))
            .clip(RoundedCornerShape(32.dp))
            .background(Color(0xFFF8B4A6))
            .border(
                3.dp,
                Brush.linearGradient(
                    colors = listOf(
                        Color.White.copy(alpha = 0.5f),
                        Color.Transparent,
                        Color.Black.copy(alpha = 0.1f),
                    ),
                    start = Offset.Zero,
                    end = Offset.Infinite,
                ),
                RoundedCornerShape(32.dp),
            )
            .padding(40.dp)
            .pointerInput(Unit) {
                detectTapGestures(
                    onPress = {
                        isPressed = true
                        tryAwaitRelease()
                        isPressed = false
                    },
                )
            },
        contentAlignment = Alignment.Center,
    ) {
        Column(horizontalAlignment = Alignment.CenterHorizontally) {
            Icon(Icons.Default.WbSunny, tint = Color.White,
                modifier = Modifier.size(48.dp))
            Spacer(Modifier.height(16.dp))
            Text("Claymorphic Card",
                fontSize = 20.sp, fontWeight = FontWeight.Bold, color = Color.White)
        }
    }
}

• Use spring(dampingRatio = 0.3f) — low damping = bouncy. This is the core of the clay feeling.
• Gradient borders work natively in Compose via Modifier.border(width, Brush.linearGradient(...), shape).
• Use Modifier.clip() before .background() to ensure the rounded corners clip content properly.

Do's and Don'ts

• DO: Use highly bouncy, spring-based animations to reinforce the soft, physical nature of the "clay."
• DON'T: Use thin, delicate fonts. They will get lost against the heavy, voluminous UI elements.

Limitations

• This is a styling reference and does not replace environment-specific validation, accessibility testing, or expert review.
• Ensure appropriate contrast ratios and responsive behaviors are verified separately.
