Aurora UI

"Ethereal, shifting lights. Like the Northern Lights trapped beneath a pane of frosted glass."

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. Blurred Color Orbs: Large, out-of-focus, highly saturated color blobs floating in the background.
2. Glassy Overlays: Foreground elements are often semi-transparent (glassmorphism) to let the aurora effect shine through.
3. Fluid Motion: The background color orbs should slowly drift, expand, and contract.

Visual DNA

• Colors: Requires dark, deep backgrounds with vibrant, luminous accents. Midnight Luxury or Yacht Club (modified to dark mode) work well, injecting bright cyan, magenta, or lime green as the glowing orbs.
• Typography: Thin, elegant sans-serifs or sophisticated serif fonts. High contrast white text.
• Layout: Keep foreground UI elements minimal to let the background remain the star.

Web Implementation

• Best achieved with absolute-positioned, heavily blurred divs behind the main content.
• CSS Example:

body {
  background-color: #0A0A0A;
  overflow-x: hidden;
  position: relative;
}

/* The Glowing Orb */
.aurora-blob {
  position: absolute;
  width: 400px;
  height: 400px;
  background: radial-gradient(circle, rgba(181,154,95,0.8) 0%, rgba(181,154,95,0) 70%);
  border-radius: 50%;
  filter: blur(80px);
  z-index: -1;
  animation: float 20s infinite ease-in-out alternate;
}

.aurora-blob.blue {
  background: radial-gradient(circle, rgba(92,107,115,0.8) 0%, rgba(0,0,0,0) 70%);
  top: 20%;
  left: 60%;
  animation-delay: -5s;
}

@keyframes float {
  0% { transform: translate(0, 0) scale(1); }
  50% { transform: translate(-50px, 100px) scale(1.2); }
  100% { transform: translate(100px, -50px) scale(0.9); }
}

/* Foreground content should be glassmorphic */
.aurora-card {
  background: rgba(255,255,255,0.03);
  backdrop-filter: blur(20px);
  border: 1px solid rgba(255,255,255,0.05);
  border-radius: 24px;
}

App Implementation

SwiftUI

struct AuroraView: View {
    @State private var animate = false
    
    var body: some View {
        ZStack {
            // Dark background
            Color.black.ignoresSafeArea()
            
            // Animated Orbs
            Circle()
                .fill(Color(red: 0.71, green: 0.60, blue: 0.37)) // #B59A5F
                .blur(radius: 80)
                .frame(width: 300, height: 300)
                .offset(x: animate ? -50 : 50, y: animate ? -100 : 0)
            
            Circle()
                .fill(Color(red: 0.36, green: 0.42, blue: 0.45)) // #5C6B73
                .blur(radius: 80)
                .frame(width: 300, height: 300)
                .offset(x: animate ? 100 : -50, y: animate ? 100 : -50)
            
            // Glassy Foreground content
            VStack {
                Text("Aurora Interface")
                    .font(.largeTitle.bold())
                    .foregroundColor(.white)
            }
            .frame(maxWidth: .infinity, maxHeight: .infinity)
            .background(.ultraThinMaterial)
        }
        .onAppear {
            withAnimation(.easeInOut(duration: 10).repeatForever(autoreverses: true)) {
                animate = true
            }
        }
    }
}

• Use Circle().blur(radius: 80...120) in a ZStack underneath the main content.
• Animate the .offset() with a very long duration (10-20 seconds).
• Use .background(.ultraThinMaterial) on foreground containers to let the colored light bleed through nicely.
