Step 2
Now just stroke across the document and you'll get 2 colors. (pick one direction to go in for a nice flow)


Do it again but maybe a bigger drag or smaller or a little bit of an added tilt. The colors will change to a totally different set.


and so on.


Keep it up until it looks good, don't overdo it.


Step 3
Now go to Layer >> New Adjustment Layer >> Gradient Map
Box should pop up, just click Ok and another should pop up.


Click the gradient and the gradient editor pops up. Pick the black/white gradient (default one)


Then set the gradient layer to "Soft Light" at 30% opacity


Now go Layer >> new adjustment layer >> gradient map. Do same steps but this time pick another default gradient you that you have in your editor.


then change the layer style and opacity of that gradient map

And now you got yourself some abstract looking thing.
