Creating this two tone color effect in AFD2

[nullpointer]

I would really like to know how to get this color effect. I've messed with most of the FX choices but can't seems to replicate this effect. Any help would be super appreciated!

Hi Null pointer,

There isn't really any way to do this automatically in Affinity Designer I'm afraid. This is a task better suited for Affinity Photo.

I apologize for my crummy initial explanation.

What I'm interested in doing is recreating the two color scheme in the characters, not the half tone dot effect. 

Thanks!

You'll need a source image to start from. One with a range of Background to Subject contrast that is high. Or you can carefully mask out the Monkeys and Men, colour the background and then invert the mask and colour the Monkeys etc.

Easiest way is with a "good" starting image.

Looks to me more to be some sort of heat map effect than two tone ...

 

... but in the OP's shown example then instead applied on silhouettes.
