If you are looking for a retro Y2K look or something futuristic, this red rainbow shadow effect should be your top choice, especially if you are a photographer or content creator.
Here is this guide, we will walk you through all the ways that are used and also effective. Also, there will be a detailed step-by-step guide on how to use top tools.
Part 1. What is the Rainbow Shadow Effect?
The red rainbow shadow effect mimics the optical dispersion of light through a prism. This shows a full spectrum rainbow that appears behind the focused subject. This can also be created via sunlight for natural effect but the majority of people rely on editing tools to make it digitally perfect.
With this, for still images such as portraits or even selfies, the overlay of color will add motion. The red photo rainbow effect also adds dimension by casting a soft or sharp hue for the face, object, and even the background. If you look beyond the visual appeal, you will find that these effects target joy, fantasy, and even sometimes nostalgia and surrealism, all these things make it a go-to thing.
If you look at the editorial spread, you will find these stories there and even on cover art, and Instagram carousels only because it has the power to evoke emotion in a naturalistic way. If you are looking to make a statement with an image, there is nothing better than the red rainbow effect on a photo.

Click and drag the gradient across your canvas. Play with linear, radial, or angle styles for different rainbow orientations.
