This tutorial will teach you how to recreate the Retro Cosmic designs made popular by James White of Signalnoise. All you need is a copy of Photoshop and some time on your hands. In this particular example we’re going to create a retro cosmic rainbow but the techniques explained can be used in combination with any shape and colour.
Start by creating a new document of 2400px by 1600px. Fill the background with a dark grey. I used #191919.
Now we’re gonna add some nice Old Grunge Paper Textures which have been released on Fudgegraphics earlier. They can be downloaded here and we’re only going to need the textures number 3 and 4. First open Paper Texture 4 and place it on top of the background layer. You might want to scale it so that it fits the document. It’s a good practice to always convert images to smart object when scaling them down.
