Common Event; Animations Affected by Screen Tint

[echomochi]

Hi all. Fairly new, so I'm still learning a lot about how to navigate RMMV.
My issue tonight is that I'm trying to create a common event which desaturates the screen while a red glow effect happens on an NPC. However, the glow animation is affected by the graying screen tint, which defeats the purpose of the animation visually standing out.
I've had no problems setting up the event, and it works as planned aside from this coloring issue. I found some forum posts about this issue in battle mode, but this is not a battle animation, just an event in the regular map. I feel like I'm missing something simple here.
I'm inserting a screenshot in case anyone wants the information, but again, the commands here behave as they are designed to. I figure I am just unaware of another feature of the program that needs to be added. If the solution is a plugin and you know of one I would appreciate the recommendation.

Thanks in advance for your time,
Echo
