rainbow gradient

[John Davidson]

The rainbow itself can be done by right clicking on your background and then clicking on “blending options” and then create a rainbow gradient like that… As for the tiles I think you could try using a distortion effect and pixelate it, and then divide each square onto a new layer and then add an inner shadow effect through blending options on each layer. I’m just a beginner but I think that should do the trick. The inner shadow may be time-consuming but it will look fantastic.

I have and advice for you ( if you use Adobe Master Collection or u have access to Adobe Illustrator)
As you can see it’s not a standard Gradient, not Linear, nor Angle…It’s exactly Mesh Gradient (unavailable in Photoshop). So you cannot make the same gradient as on the image simply, you would have to combine Gradient, Blurring, Smudging…
It’s far easier to do it with Adobe Illustartor .
You can use Mesh Tool , making such a gradient will take up to 1 minute in Illustartor, bacause Mesh Tool is extremely powerful and simple tool ???? One more idea is to copy it then to Photoshop as Smart Object , then u will be able to make other operations in Photoshop with possibility to change the gradient in Illustator anytime you want 😉
