How to use Add a Rainbow Filter to an Image
- 1. Pick your photo. Drop the image you want to color onto the input pane. Portraits and avatars are the most common candidates, and the horizontal gradient is applied edge to edge across whatever you load.
- 2. Adjust the Rainbow opacity. Use the Rainbow opacity slider to blend the gradient with the photo underneath. Around 30 to 40 percent keeps faces clearly visible, while higher values turn the image into a bold color statement.
- 3. Save the result. The blended preview updates as you drag the slider. When the balance between the photo and the rainbow wash looks right, download the image and set it as your avatar or post it.
When to use Add a Rainbow Filter to an Image
Add a Rainbow Filter to an Image lays a horizontal rainbow gradient across a picture at whatever strength you choose. The classic use is a Pride-themed profile photo, but the same left-to-right color wash works for event branding, playful edits and any design that wants a full spectrum without hand-building a gradient layer.
- Pride month profile pictures. Every June, avatars across Slack, LinkedIn and Twitter get the rainbow treatment. Upload your current photo, set opacity so your face still reads at thumbnail size, and download the updated avatar in under a minute.
- Team-wide event avatars. For a company celebrating Pride or a diversity event, running everyone's headshot through the same filter at the same opacity produces a coordinated set without asking anyone to learn an editor.
- Colorful covers and banners. A playlist cover, stream banner or community header can start as any photo and gain instant color identity from a strong rainbow wash pushed past 60 percent opacity.
