Rainbow Glitch Effect as seen in Photoshop

[ESPR]

There is an effect that is quite trendy at the moment in surreal glitch art.

Basically it creates brushstrokes in rainbow colours, that look like its melted.

 

Here is an example:

You can find an explanation how this effect is done here (at 3:30):

In PS you need an empty layer above your image and a Hue Saturation Adjustment Layer on top. Then you paint with the Mixer Brush on the empty layer and the rainbow glitch magic happens.

 

Can we do this in Affinity Photo ? If so, how ?

Hi ESPR,

I can't see away to do this.  I've tried setting up everything in Affinity the same as shown in the above tutorial and can't get it work.  It's possible i'm missing something and i'm sure if anyone knows of a method they will post

Thanks for looking into this, its probably something that is specific to the way Photoshop behaves. It almost feels like joyriding a behaviour that was not intentional in the first place, regarding the Mixer Brush and somebody turned it into an effect.

I guess not all things can be replicated.
