Color Splash (also known as selective color or color isolation) is a photographic technique where a single color or color range is preserved while the rest of the image is converted to black and white. This draws the viewer's eye to the colored areas, creating a dramatic and artistic effect. It's widely used in wedding photography, product shots, and artistic portraits to emphasize specific elements like a red rose, blue eyes, or a colorful outfit.

Upload your image, then choose the color you want to keep using the color picker, preset swatches, or the eyedropper tool (click directly on the original image). The tool analyzes every pixel, comparing its hue to your selected color. Pixels within the tolerance range retain their original color; all others are converted to grayscale. Adjust the Tolerance and Feather sliders to fine-tune the result, then download your image. Everything runs locally in your browser — no upload to any server.

Tolerance determines how strictly the tool matches colors to your selected hue. A lower tolerance (10–30%) keeps only colors very close to your chosen shade — ideal for isolating a specific red apple among various reddish objects. A higher tolerance (60–90%) preserves a broader range of similar hues, which works well when lighting varies across the subject. We recommend starting at 40% and adjusting based on your image.

Feather (softness) creates a smooth transition between colored and grayscale areas. Without feathering, the boundary can look harsh and pixelated. Increasing the feather value blends the edges gradually, producing a more natural, professional-looking result. Think of it as a "gradient zone" where pixels partially retain their color. A value of 15–25% usually gives the best balance between crispness and smoothness.

By default, the tool keeps your selected color and turns everything else grayscale. Enabling Invert reverses this: your chosen color becomes grayscale, while all other colors remain vibrant. This is useful for creative effects — for example, desaturating a distracting background color while keeping the rest of the scene colorful.

No. This tool processes everything client-side — your image never leaves your device. The entire color splash effect is computed locally using JavaScript and the HTML5 Canvas API. Your privacy is fully protected. You can use this tool offline once the page is loaded.

The tool accepts JPG, PNG, WebP, and most common image formats. The processed result is downloaded as a high-quality PNG file, preserving transparency if your original image had it. For best results, use images with good contrast between the subject color and the background.

① Choose images where the subject has a distinct, saturated color against a more muted or varied background. ② Use the eyedropper to sample the exact shade from your image. ③ Start with Tolerance around 35–50% and Feather around 20%, then tweak. ④ For portraits, isolate eye color or a piece of clothing. ⑤ Avoid images where the subject color appears heavily in the background — the effect works best with clear color separation. ⑥ Try the Invert toggle for unexpected artistic results!
