What is Color Splash?
Color Splash is a selective color photo effect tool that lets you keep one or more specific colors in your image while converting everything else to black and white (grayscale). This creates a dramatic, eye-catching effect that draws attention to the colored elements in your photo.
Whether you want to highlight a red rose against a gray background, make a blue car pop out from a desaturated street scene, or isolate multiple colors for a creative composition, this tool gives you full control over the effect with intuitive controls.
How It Works
The tool uses HSL (Hue, Saturation, Lightness) color space to intelligently match colors. Unlike simple RGB matching, HSL-based comparison produces more natural and visually pleasing results by separately considering the hue (color), saturation (intensity), and lightness of each pixel.
How to Use
Upload Your Image
Load your image by dragging and dropping it onto the upload area, clicking to browse your files, or pressing Ctrl+V to paste from your clipboard.
- Supported formats: JPEG, PNG, WebP, GIF, and BMP

Frequently Asked Questions
What is the Color Splash effect?
Color Splash (also known as selective color or color pop) is a photo editing technique where you keep one or more specific colors in an image while converting all other colors to grayscale. It is commonly used to draw attention to a particular subject or element in a photograph.
How do I select which colors to keep?
Simply click anywhere on your image with the eyedropper tool (the default mode). The color at that point will be preserved, and everything else will become black and white. You can click multiple times to keep several different colors.
What does the tolerance slider do?
Tolerance controls how closely a pixel's color must match your selected color to be kept. A low tolerance only keeps very similar shades, while a high tolerance preserves a wider range of related colors. Start with the default value and adjust until you are satisfied with the result.
Precise Selection
- Only exact color matches
- Narrow shade range
- More manual refinement needed
Broad Selection
- Similar shades included
- Wide color range
- Faster initial results
What is edge softness?
Edge softness controls the transition between colored and grayscale areas. At zero, you get a sharp, hard edge. Increasing the value creates a smooth, gradual blend that looks more natural and professional.
When should I use the brush tools?
Brush tools are useful for fine-tuning areas where automatic color matching does not give you the desired result. Use the restore brush to bring back color in specific spots, or the grayscale brush to remove unwanted color that the tolerance kept.
- Fixing edges around complex objects
- Adding color to small missed areas
- Removing color from unwanted regions
- Creating artistic custom effects
Can I undo my changes?
Yes. Press Ctrl+Z (or Cmd+Z on Mac) to undo your last action. The tool keeps up to 30 steps of history. You can also click the Reset button to start over completely.
What image formats are supported?
You can upload JPEG, PNG, WebP, GIF, and BMP images. For export, you can choose between PNG (lossless), JPEG, or WebP with adjustable quality.
| Format | Input Support | Output Support | Best For |
|---|---|---|---|
| PNG | Yes | Yes | Lossless quality, transparency |
| JPEG | Yes | Yes | Smaller file sizes, photos |
| WebP | Yes | Yes | Modern format, balanced quality/size |
| GIF | Yes | No | Input only |
| BMP | Yes | No | Input only |
Is there a file size limit?
Since all processing happens in your browser, there is no upload limit. However, very large images may take longer to process depending on your device's performance.
