FAQ

Frequently Asked Questions

Is my uploaded photo safe?

Absolutely. Image Studio is a privacy-first web application. All image rendering and rainbow filtering happen directly inside your web browser. Your photos are never uploaded to external servers, ensuring total privacy.

Can I customize the colors of the rainbow?

Yes! You can use our standard seven-color rainbow scheme (Red, Orange, Yellow, Green, Blue, Indigo, Violet), invert the color order, or build your own custom color palette from scratch using our integrated color picker.

What is the difference between the full overlay and colorful-pixel mode?

The full overlay applies a beautiful rainbow haze across your entire photo while preserving its natural luminosity. The colorful-pixel mode intelligently applies the rainbow effect only to colored pixels, keeping your whites, grays, and black areas clean and unaffected.

Can I adjust the angle, position, and repetitions of the rainbow?

Yes, you have complete creative control. You can manually input or interactively drag to adjust the angle of linear gradients, click to position the center of radial gradients, set the radial direction, and adjust the number of rainbow cycles (repetitions) to get the exact look you want.
