Ripple Gradient Generator

A ripple gradient renders the visual effect of water disturbed by a drop falling on its surface: concentric expanding rings that propagate outward from a centre point. The rings are not solid circles drawn on top of a flat gradient; they are actual wave disturbances in a colour field, calculated using the same maths that describes real water waves.

The aesthetic reads as calm, scientific, and slightly ceremonial. Meditation apps use ripple gradients for guided breathing exercises. Water and hydration brands use them on product packaging. Scientific publications use them as section dividers. The visual signals reflection, depth, and slow time, all without literal photography.

The Gradients.design ripple generator uses a real wave equation rather than a Photoshop ripple filter. The difference matters when you scale to large sizes or when multiple ripples overlap: real wave physics produces interference patterns (the way two real ripples in a pond interact) that filters cannot reproduce. Export at any resolution and the wave behaviour holds up.

Most "ripple" effects in design software are post-processing filters that displace pixels along a radial sine pattern. They look fine at small sizes and with single ripples, but they have three limitations: amplitude does not decay correctly with distance, multiple ripples do not interfere realistically, and the wave fronts get visibly stepped at large export sizes.

Real wave physics fix all three. The Gradients.design ripple shader implements the 2D wave equation, which models how disturbances propagate through a medium. Key properties of the simulation:

• Amplitude decay. Wave amplitude decreases as 1 divided by the square root of distance from source. Real ripples fade naturally; faked filters maintain constant amplitude or use linear decay.
• Phase coherence. Wave fronts move at constant speed regardless of amplitude, and the spacing between fronts remains constant. Faked filters often warp these.
• Interference. When two ripples overlap, the amplitudes add. At points where peaks meet peaks, the result is brighter (constructive). At points where peaks meet troughs, the result cancels (destructive). The studio renders these interference patterns correctly.
• Resolution-independence. Because the wave equation is continuous, the output holds up at any export size. Filters using fixed pixel patterns reveal stepping at 4K and above.

The cost is GPU work. The shader runs the wave field calculation per pixel per frame, which is roughly 100 million floating-point operations per second on a 1080p canvas at 60fps. WebGL handles this on any device made in the last decade; older devices may see reduced live-preview quality but export remains full quality.

1. Open the ripple editor. Visit the free ripple gradient generator. The canvas opens with a default ripple drifting across a colour gradient.
2. Set ripple count. Pick 1 to 8 ripple sources. Each source produces its own expanding rings; multiple sources create interference patterns where they overlap.
3. Tune speed and amplitude. Slow speed reads as meditative; fast as energetic. Subtle amplitude reads as still water; dramatic amplitude reads as stormy or disturbed.
4. Export. PNG up to 8K, or animated MP4 and WebM with seamless loop on Pro plans.

Single-source ripple gradients look like a flat colour gradient with concentric rings. They work for simple compositions but lack visual complexity. Multi-source ripple gradients produce interference patterns that are much more visually interesting.

When two ripple sources overlap, the wave amplitudes add at every point in the canvas. At some points the peaks align (constructive interference), and the visible ring is brighter. At other points the peaks of one source meet troughs of another (destructive interference), and the rings cancel. The result is a pattern of bright and dark zones forming a diagonal lattice across the canvas.

For more sources, the interference pattern becomes more complex. Three sources at the vertices of a triangle produce a triangular tiling of bright zones. Four sources at corners of a square produce a square tiling. The studio handles up to 8 sources; beyond that the patterns become too complex to be visually clear.

This is the visual that physics textbooks use to demonstrate wave interference, and one reason scientific publications reach for ripple gradients: the technique is genuinely demonstrating real physics, not just decorative shapes.

Water and wellness brands have specific visual requirements: the marketing should feel cool, refreshing, calming, and clean. Ripple gradients hit all four directly because the visual literally references water.

Recommended workflow for water-brand marketing:

1. Pick a cool blue palette: pale aqua (#dbeafe), soft cyan (#7dd3fc), deep ocean (#0c4a6e). Three colours is plenty.
2. Set 2 to 3 ripple sources positioned in the upper third of the canvas (mimics water filling from above).
3. Use slow speed (around 0.4x default) and subtle amplitude. The ripples should read as gentle, not stormy.
4. Export PNG at 4K for web, 8K for print marketing or premium packaging.
5. In Figma or Photoshop, place product image on top. Add a soft shadow under the product to ground it.

For wellness and spa brands, shift the palette warmer: pale coral, amber, soft pink. Same workflow, different colour mood. The ripple pattern reads differently with warm tones (intimate, relaxing rather than cool and clean), but the wave physics remain identical.

• Meditation app backgrounds. Slow ripples read as breathing exercises and contemplative states.
• Water and hydration brand marketing. Liquid IV, Cure Hydration, premium bottled water brands.
• Spa and wellness branding. Bath products, spa marketing, relaxation services.
• Scientific visualisation aesthetics. Especially for physics, marine biology, and fluid dynamics adjacent brands.
• Loading screen animations. Concentric ripples reads as "thinking" or "processing" in a way more elegant than a spinner.
• Calm video intros. 5 to 10 second ripple intros work well for thoughtful editorial video content.
• Music streaming backplates. Ambient and classical genres pair well with ripple visuals.
• Brand identity for therapy and mental-health apps. The visual rhythm matches the brand promise.

Pure-CSS ripple effects exist but produce visibly fake results. The standard technique is a radial-gradient with animated background-position, which produces a single ring that expands once:

.ripple {
  background:
    radial-gradient(
      circle at 50% 50%,
      transparent 30%,
      rgba(125, 211, 252, 0.4) 35%,
      transparent 40%
    ),
    linear-gradient(135deg, #0c4a6e, #1e3a8a);
  background-size: 200% 200%, 100% 100%;
  animation: ripple-expand 4s ease-out infinite;
}

@keyframes ripple-expand {
  0% { background-size: 0% 0%, 100% 100%; }
  100% { background-size: 300% 300%, 100% 100%; }
}

This produces a passable single-ripple effect in pure CSS. Multi-ripple interference is impossible to reproduce in CSS because the technique needs per-pixel wave-field calculation. For real multi-source ripple compositions, export from the studio as PNG or MP4.

1. Amplitude too high. Maximum amplitude reads as stormy or chaotic. Real-water-feel amplitude is subtle; the rings should be visible but not aggressive.
2. Too many sources. 8 sources is the maximum and rarely the right choice. 2 to 4 sources produce visually clearer interference patterns.
3. Wrong palette for the brand. Cool blues for water brands; warm tones for spa and wellness; monochrome for scientific publications. Match palette to brand temperature.
4. Speed too fast. Fast ripple speeds read as agitated water, which contradicts the usual brand message. Stick to slow speeds for marketing use.
5. Pure black background. Ripple gradients need a colour gradient underneath the rings to be visible. Pure black flattens the visual.
6. Centring all sources. Multiple sources at the same point produce a single visible ripple, not interference. Offset sources by at least 20 percent of canvas width to see distinct patterns.
