Partial rainbow add a partial rainbow visible only on the right side, fading into clouds on the left 20s

How it works

  1. Upload your outdoor photo

    Drop your landscape or outdoor photo into EditThisPic. JPG, PNG, WebP up to 7MB. Best results come from photos with visible sky and natural lighting. Cloudy or post-storm skies work especially well for realistic rainbow effects.

    Expect: Simple rainbow placement: 15-30 seconds. Complex scenes with multiple elements or specific positioning: may need 2-3 refinements for perfect placement.

  2. Describe the rainbow you want

    Type your instruction: 'add a natural-looking rainbow across the sky from left to right' or 'add a faint double rainbow in the upper sky.' Be specific about arc position, intensity (faint, vibrant, subtle), and placement. No marking needed—the AI understands sky context and natural rainbow physics. Include details like 'with sunlight breaking through clouds' for even more realism.

    Tip: Mention weather context like 'post-storm rainbow' or 'early morning rainbow' for AI to match lighting conditions naturally.

    Copy one of these to get started:

    Subtle single rainbow add a faint rainbow in the upper third of the sky, soft pastel colors, early morning light
    Try This →
    Double rainbow effect add a double rainbow with the main rainbow bright and vivid, secondary rainbow fainter above it, both arcing from left to right
    Try This →
    Partial rainbow arc add a partial rainbow visible only on the right side of the sky, fading into clouds on the left, medium intensity

    3 more prompts
    Low horizon rainbow add a low rainbow near the horizon with the arc barely visible, touching the ground at both ends, golden hour lighting
    Try This →
    Dramatic vivid rainbow add a highly saturated rainbow with extremely vibrant reds, oranges, yellows, greens, blues, purples arcing prominently across dark storm clouds
    Try This →
    Rainbow with sunbeams add a rainbow in the right side of the sky with sun rays breaking through clouds on the left, creating natural post-storm atmosphere
    Try This →

  3. Generate and review

    AI analyzes your sky, lighting conditions, and cloud formations to place a realistic rainbow. Check the arc shape, color intensity, and how it blends with existing weather conditions. Zoom in to verify the rainbow's edges fade naturally into the sky.

  4. Refine with markers if needed

    If the rainbow needs repositioning or you want to adjust specific areas where it appears too strong or faint, tap markers on those spots and regenerate. This is optional—most rainbow additions work without markers. Use markers to specify exact arc endpoints or intensity zones.

    Tip: Markers help when you want the rainbow to start or end at a specific landscape feature like a mountain or tree line.

Detailed Guides by Scenario

📷

Home & Interior Design

Preview how rainbow would look in a room or space before committing to a purchase or renovation.

Common Scenarios

  • Visualizing rainbow in a living room, bedroom, or office before buying
  • Creating client mockups that show rainbow in their actual space
  • Comparing different placements of rainbow in renovation plans

Best Practices

  • Upload a well-lit, straight-on photo of the room for the most realistic result
  • Specify the size and position — e.g., 'add a large rainbow on the left wall'
  • Match the room's lighting in your prompt: 'warm lighting' for evening shots, 'natural daylight' for window-lit rooms
📷

Creative & Social Content

Use rainbow to create eye-catching content for social media, digital art, or personal projects.

Common Scenarios

  • Adding rainbow to photos for unique social media posts that stand out in feeds
  • Creating fantasy or composite images that incorporate rainbow for art projects
  • Making holiday or themed content by placing rainbow in seasonal photos

Best Practices

  • Be specific about the style — 'realistic rainbow' vs. 'illustrated rainbow' gives very different results
  • Use reference images when you want the AI to match a particular look
  • For social content, try unusual placements that create a surreal or humorous effect
📷

Professional & Marketing Use

Incorporate rainbow into marketing materials, presentations, and product catalogs without expensive photo shoots.

Common Scenarios

  • Adding rainbow to product mockups and marketing banners
  • Creating presentation slides that show rainbow in context
  • Building a catalog of variations that feature rainbow in different settings

Best Practices

  • Use high-resolution source images — marketing materials demand sharp details
  • Keep brand guidelines in mind: specify colors and style that match when adding rainbow
  • Generate multiple versions and A/B test which placement performs best in ads

If something looks off

Rainbow looks artificial or too bright

Why: The AI defaulted to maximum saturation without context about your lighting conditions. Natural rainbows vary in intensity based on sun angle and moisture.

Try: Regenerate with: 'add a subtle rainbow with soft pastel colors, low saturation' or 'add a faint rainbow barely visible in the sky'
Try This →

Tip: Use words like 'faint', 'subtle', or 'soft' to reduce intensity. Mention 'early morning' or 'late afternoon' for more natural color.

Rainbow arc doesn't follow natural curve

Why: The AI may have misinterpreted perspective or horizon line in your photo. Rainbow arcs should follow the sky's natural dome shape.

Try: Add markers at the two points where you want the rainbow to start and end (usually near horizon), then regenerate with the same prompt
Try This →

Tip: Markers tell the AI exactly where the rainbow endpoints should touch down.

Rainbow appears in wrong position or cuts through objects

Why: The AI placed the rainbow generically without understanding your composition. Rainbows should appear behind distant objects or in open sky.

Try: Be more specific: 'add a rainbow in the upper right sky above the mountain peaks' or 'add a rainbow behind the trees on the left side'
Try This →

Tip: Mention landscape features in your prompt to help position the rainbow naturally.

Colors don't match my photo's lighting

Why: Rainbow colors should complement your existing lighting—warm for sunset, cooler for overcast, vivid for post-storm sun.

Try: Include lighting context: 'add a rainbow with warm tones matching golden hour' or 'add a rainbow with cool colors for overcast day'
Try This →

Tip: Mentioning your photo's lighting conditions (golden hour, overcast, post-storm) helps AI match color temperature.

Double rainbow has incorrect color order

Why: Secondary rainbows naturally have reversed color order (red on inside). If this wasn't applied, the AI may need more specific instruction.

Try: Use: 'add a double rainbow with secondary rainbow having reversed color order, red on the inside, fainter than the primary'
Try This →

Tip: Most users don't notice, but photographers appreciate scientifically accurate double rainbows.

Quick answers

Do I need to mark the sky before adding a rainbow?

No! Just describe what you want: 'add a natural rainbow across the sky from left to right' or 'add a faint rainbow in the upper sky.' The AI understands sky context. Only use markers when you need to specify exact arc endpoints or adjust intensity in specific zones.

How do I make the rainbow look natural and not fake?

Use descriptive words about intensity and context. Instead of just 'add rainbow', try 'add a faint post-storm rainbow with soft colors' or 'add a subtle rainbow visible in the upper sky.' Mentioning weather context (post-storm, early morning, golden hour) helps AI match your photo's lighting. Lower intensity rainbows almost always look more natural than vivid ones.

What is the best free AI tool to add rainbows to photos?

EditThisPic's AI Rainbow Adder handles natural rainbow placement without complex masking or layers. Just describe the rainbow you want, and AI adds it in 15-30 seconds with realistic color gradients, natural arc curves, and proper sky blending. Free to try with no signup or watermark.

Can I add double rainbows or partial rainbows?

Yes! For double rainbows, describe both arcs: 'add a double rainbow with bright primary arc and fainter secondary rainbow above it.' For partial rainbows, specify visibility: 'add a partial rainbow visible only on the right side, fading into clouds.' The AI handles proper color order and intensity differences automatically.

Why does my rainbow look too bright compared to the rest of the photo?

The default is often maximum saturation. Add intensity descriptors to your prompt: 'faint', 'subtle', 'soft pastel colors', or 'low saturation rainbow.' You can also mention lighting conditions like 'matching overcast lighting' or 'complementing golden hour tones' to help AI adjust vibrancy to your scene.
