What is Color Splash?

Pick the colors you want to keep and everything else goes grayscale. Click to sample a color, hit Add Another Color to stack more, tune each tolerance, soften the edges, and download the result.

Click anywhere on the photo to sample the colour you want to preserve. The tool reads that pixel's hue in HSL space and turns everything outside the tolerance range to grayscale. Low-saturation picks like dark blues or near-blacks are matched by RGB distance instead, so muted target colours aren't wiped out alongside the background.

How to use

1. Upload a photo and click on the color you want to keep.
2. Adjust the color tolerance slider to fine-tune which shades are preserved.
3. Preview the effect and download the color splash image.

When to use

• Highlighting a red dress or a single balloon in an otherwise grey street photo.
• Making product shots pop on a website by isolating brand colours from a distracting room.
• Drawing the eye to one element in a children's book illustration or wedding photo.

Result

Upload a photo of a red rose in a garden — click on the rose's red, set tolerance to 30, and the entire photo turns grayscale except for the red petals.

FAQ

Why does my picked colour also disappear when I click on it?

Tolerance is probably too low. The picker uses an exact hue, but real photos have shading across many shades. Raise the tolerance slider so neighbouring hues (the lit and shadowed parts of the object) survive too.

How do I keep dark or near-black objects without the whole image staying coloured?

When you pick a low-saturation colour the tool switches to RGB distance matching, which keeps dark navy or grey tones but won't catch unrelated darks. Combine a moderate tolerance with the lasso of a darker tone for the best result.

Can I select more than one colour to keep?

Yes. After your first pick the button switches to Add Another Color, so you can stack as many hues as the photo needs. Each colour gets its own tolerance slider, and a shared softness slider feathers the grayscale transition around every kept hue at once.

What image formats does it accept and export?

Upload PNG, JPEG, WebP or GIF (first frame). The export is a PNG at the original resolution, preserving any alpha. Very large images may slow processing on mobile because every pixel is examined.

Is my photo uploaded somewhere when I run the effect?

No. The image is decoded and processed pixel by pixel right on your device, then saved to disk when you click download. Nothing leaves your machine, which matters with personal photos.
