user36337: Summary
I'm making an artwork and here's how it goes in a nutshell: A fictional movie scene that was (1) shot on film in the '60s, (2) restored in VHS format in the '80s or '90s, and (3) restored again in a digital format in the present day.
Now, from that second bit onward, here's how I assumed it went in practical terms: In the '80s or '90s, the movie (my artwork) was restored in a VHS format (with PAL standard) by a telecine machine using the release print. At the present day, the tape was restored in a digital format by an RCA-to-USB converter that connects the VCR to a computer.
In order to simplistically replicate this process, I've been trying to split my material up into 3 separate YUV channels and work from there intuitively, since I believe it's the luma and chroma signals that make up this analog video effect, before the video gets automatically decoded back into RGB (correct me if I'm wrong). This is where the question comes in: What's the proper way to separate the YUV components of my clips for this particular effect?
Additional info

Here's the current state (top) and a rough sketch of the desired result (bottom):


I want to separate the channels like this (I might be wrong):

I'm currently using Adobe Premiere Pro 2017.
I'm not looking for plugins or jumping to other softwares.
I've tried:

Separating 3 clips of Red-Luma, Blue-Luma, and Luma components onto 3 video tracks using Channel Mixer effect: The math way. I skipped because it returned an image that looks pink tinted, although there was an RGB-to-YUV conversion formula involved.
Separating 3 clips of Red, Green and Blue components onto 3 video tracks using RGB Curves effect: The intuitive way. I skipped because it was obvious that I was working on RGB components instead of YUV, although there's one tutorial using this method.
Separating 4 clips of Red, Green, Blue, and Luma components onto 4 video tracks using RGB Curves and Luma Curve effects: The intuitive way. I'm considering this because it returned the image back to normal.




user1950: Here's the current image (left) side by side with the desired image.

To get there I opened up lumetri scopes and tweaked the RGB curves until the LHS matched the RHS -ish.
Here's the histogram before:

and after:

This is how the curves looked. Could probably do with more work, but basically I'm reducing the exposure mostly in the blue, and also taking out some of the blacks, particularly in the blue and green.

I ulso reduced the saturation, moreso in the lighter parts of the picture

To do it justice it needs some film grain, and some softness. PP doesn't have a built-in grain effect, and its noise effect is pretty feeble. I added about 7% noise and a 5.6 px gaussian blur. If I was to round trip to AE I'd go for the grain effect there, and possibly some camera lens blur.
