Why is my sprite color darkening in game?

I am using the Paper2D preset.

The sprites in my game are visibly darkened when in-game versus in the editor. They are using the DefaultSpriteMaterial already in Unreal Engine. I have every Post Process setting switched off in my Pawn’s camera, but haven’t messed around with the Project Settings much.

In-editor (correct color):


In-game (darkened):


How can I remove this darkening so that the color is exactly the color of its source texture when in-game?


I figured out some sort of solution;


I added this to the BeginPlay event and the colors are correct now. I do not know if this has any drawbacks, however.
