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: #a05a6c; /* 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())
    }
}

• A custom font like Nunito or Quicksand is practically required. System fonts are often too rigid.
• 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).
