How to achieve such color correction?

[arxip12g (Null)]

I was faced with the question of how such a picture is possible from one copy BUCKSHOT ROULLETE

It’s BUCKSHOT FRENZY

[NEW ITEMS] BUCKSHOT FRENZY

screenshos from game and it’s very similar to the original

and another example

it’s A Nostalgic Hangout Game
Probably the same method is used

I had an idea of how this could be done, but the idea didn’t go further than the idea and the idea was to do it somehow through the viewport frame

If anyone has experience with this or rough concepts for this please help

thanks if anyone can help with this
