Soft Pastel Design

> "Calm, airy, and gentle. A low-stress interface built on washed-out, cheerful hues."

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. Desaturated, High-Lightness Colors: Every color is mixed with a heavy amount of white.

2. Soft, Rounded Edges: Border radii are large and friendly.

3. Airy Spacing: Generous whitespace prevents the soft colors from feeling muddy or crowded.

Visual DNA

• Colors: Mint green, baby blue, blush pink, lavender, and buttercream yellow. Use a warm, slightly off-white background (e.g., #FFFBF7) rather than clinical #FFFFFF.
• Typography: Soft, rounded sans-serifs (Quicksand, Nunito) or elegant, low-contrast serifs. Avoid aggressive, ultra-bold fonts.
• Shadows: Very soft, large-spread shadows, often tinted with the pastel color rather than black.

Web Implementation

• CSS Example:

:root {
  --pastel-bg: #FFFBF7;
  --pastel-pink: #FFD1DC;
  --pastel-blue: #AEC6CF;
  --pastel-green: #B7E4C7;
  --pastel-text: #4A4A4A; /* Soft dark grey, NOT pure black */
}

body {
  background-color: var(--pastel-bg);
  color: var(--pastel-text);
  font-family: 'Nunito', sans-serif;
  line-height: 1.6;
}

.pastel-card {
  background-color: #ffffff;
  border-radius: 24px;
  padding: 40px;
  /* Tinted, very soft shadow */
  box-shadow: 0 20px 40px rgba(174, 198, 207, 0.15); 
}

.pastel-pill {
  background-color: var(--pastel-pink);
  color: #703347; /* Darker version of the pink for contrast */
  border-radius: 50px;
  padding: 8px 24px;
  font-weight: 700;
  display: inline-block;
}

.pastel-btn {
  background-color: var(--pastel-blue);
  color: #2b5563; /* Darker text */
  border: none;
  border-radius: 12px;
  padding: 16px 32px;
  transition: transform 0.2s;
}
.pastel-btn:hover {
  transform: translateY(-2px);
  box-shadow: 0 10px 20px rgba(174, 198, 207, 0.4);
}

App Implementation

SwiftUI

struct SoftPastelView: View {
    // Pastel Palette
    let bg = Color(hex: "FFFBF7")
    let pink = Color(hex: "FFD1DC")
    let blue = Color(hex: "AEC6CF")
    let textDark = Color(hex: "4A4A4A")
    
    var body: some View {
        ScrollView {
            VStack(spacing: 32) {
                // Pastel Card
                VStack(alignment: .leading, spacing: 16) {
                    Text("Calm & Airy")
                        .font(.custom("Nunito-Bold", size: 28))
                        .foregroundColor(textDark)
                    
                    Text("Generous whitespace and soft corners prevent the desaturated colors from feeling muddy.")
                        .font(.custom("Nunito-Regular", size: 16))
                        .foregroundColor(textDark.opacity(0.8))
                        .lineSpacing(6)
                }
                .padding(40)
                .frame(maxWidth: .infinity, alignment: .leading)
                .background(Color.white)
                .cornerRadius(32) // Soft, large radius
                // Tinted pastel shadow instead of black/gray
                .shadow(color: blue.opacity(0.2), radius: 30, y: 15)
                
                // Pastel Button
                Button(action: {}) {
                    Text("Gentle Action")
                        .font(.custom("Nunito-Bold", size: 18))
                        .foregroundColor(Color(hex: "2B5563")) // Darker contrast of the blue
                        .frame(maxWidth: .infinity)
                        .padding(.vertical, 20)
                        .background(blue)
                        .cornerRadius(20)
                }
            }
            .padding(24)
        }
        .background(bg.ignoresSafeArea())
    }
}

• Nunito and Quicksand are optional choices; system rounded fonts and readable fallbacks also work.
• The shadow(color:) must be tinted with one of your pastel palette colors, never black or gray.
• Corner radii should be very large (20-32).

Flutter

class SoftPastelScreen extends StatelessWidget {
  final Color bg = const Color(0xFFFFFBF7);
  final Color pink = const Color(0xFFFFD1DC);
  final Color blue = const Color(0xFFAEC6CF);
  final Color textDark = const Color(0xFF4A4A4A);

  @override
  Widget build(BuildContext context) {
    return Scaffold(
      backgroundColor: bg,
      body: SingleChildScrollView(
        padding: const EdgeInsets.all(24.0),
        child: Column(
          children: [
            // Pastel Card
            Container(
              width: double.infinity,
              padding: const EdgeInsets.all(40),
              decoration: BoxDecoration(
                color: Colors.white,
                borderRadius: BorderRadius.circular(32), // Soft edges
                boxShadow: [
                  // Tinted shadow
                  BoxShadow(color: blue.withOpacity(0.2), blurRadius: 30, offset: const Offset(0, 15))
                ],
              ),
              child: Column(
                crossAxisAlignment: CrossAxisAlignment.start,
                children: [
                  Text('Calm & Airy', style: TextStyle(fontFamily: 'Nunito', fontSize: 28, fontWeight: FontWeight.bold, color: textDark)),
                  const SizedBox(height: 16),
                  Text('Generous whitespace and soft corners.', style: TextStyle(fontFamily: 'Nunito', fontSize: 16, height: 1.6, color: textDark.withOpacity(0.8))),
                ],
              ),
            ),
            const SizedBox(height: 32),
            
            // Pastel Button
            ElevatedButton(
              onPressed: () {},
              style: ElevatedButton.styleFrom(
                backgroundColor: blue,
                foregroundColor: const Color(0xFF2B5563), // Darker text for contrast
                minimumSize: const Size(double.infinity, 60),
                shape: RoundedRectangleBorder(borderRadius: BorderRadius.circular(20)),
                elevation: 0, // Remove default harsh shadow
              ),
              child: const Text('Gentle Action', style: TextStyle(fontFamily: 'Nunito', fontSize: 18, fontWeight: FontWeight.bold)),
            ),
          ],
        ),
      ),
    );
  }
}

• Disable elevation on Flutter buttons and cards if you want to apply custom tinted drop shadows. Default elevations cast black shadows.

React Native

const SoftPastelScreen = () => {
  const colors = {
    bg: '#FFFBF7',
    blue: '#AEC6CF',
    textDark: '#4A4A4A'
  };

  return (
    <ScrollView style={{ flex: 1, backgroundColor: colors.bg, padding: 24 }}>
      
      {/* Pastel Card */}
      <View style={{
        backgroundColor: '#FFFFFF',
        borderRadius: 32,
        padding: 40,
        marginBottom: 32,
        // iOS tinted shadow
        shadowColor: colors.blue, shadowOffset: { width: 0, height: 15 },
        shadowOpacity: 0.2, shadowRadius: 30,
        // Android tinted shadow (Requires Android 9+)
        elevation: 10, // shadowColor already set above
      }}>
        <Text style={{ fontFamily: 'Nunito-Bold', fontSize: 28, color: colors.textDark, marginBottom: 16 }}>
          Calm & Airy
        </Text>
        <Text style={{ fontFamily: 'Nunito-Regular', fontSize: 16, lineHeight: 26, color: colors.textDark, opacity: 0.8 }}>
          Generous whitespace and soft corners prevent the desaturated colors from feeling muddy.
        </Text>
      </View>

      {/* Pastel Button */}
      <TouchableOpacity style={{
        backgroundColor: colors.blue,
        borderRadius: 20,
        paddingVertical: 20,
        alignItems: 'center'
      }}>
        <Text style={{ fontFamily: 'Nunito-Bold', fontSize: 18, color: '#2B5563' }}>
          Gentle Action
        </Text>
      </TouchableOpacity>
      
    </ScrollView>
  );
};

• Make sure you are using a soft, non-pure-white background (#FFFBF7) so that pure #FFFFFF cards pop nicely against it without harsh borders.
• Tinted shadows work on Android 9+ via shadowColor combined with elevation.

Jetpack Compose

                .shadow(
                    elevation = 20.dp,
