Sounds like it's time for me to over-analyze this, lol.
As seen in the second image, traditionally for higher levels of approval the pauldron color has closely matched the paint on the armor. Even in the Mandalorian version the colors match pretty close. However, in the videogame image they are not even in the same ballpark. Not a fan of this, to be honest.
Videogame Current CRL Mandalorian
We have to consider that the game image references are at least 12 years old, and now that we have more solid, updated ones I personally would steer clear of the older version with the mismatched hues of red.
Another thing to consider is that in the older version (1st pic) the paint is more of a Burgundy color and lines are not as crisp and clean as the new ones (2nd pic). Some "battle damage" is necessary, but the game paint job is just a mess.
The paint details (3rd pic) in the Mandalorian are different as well. As seen in the last image it extends down the front of the thigh cover strip, covers the center of the sniper knee and there is a design on the hand guards.
I am really liking the newer version, and considering the updated references I will be suggesting that we closely follow these when it comes time to change the CRL, including the stitching/seam on the pauldron. While we can't dictate a particular paint color, my suggestion will be a "Maroon" red or something close. Same for the pauldron.
As for current approvals (Levels 2 and 3) it is my feeling that the pauldron should (closely) match the paint.
