Colour or Lighting of Character and Tilemap is paler from what I expect

(Eng Bad)
Hi, I’m trying to create my first game by UE4. It’s a 2D RPG game,
I’m having a problem with the colour or lighting (idk too) of the characters and the Tilemap that are paler than they should be. I didn’t place any light. Most of the project setting is the default setting. I’ve never posted any topic before, So if you need any information about settings or anything about the game, please tell me.
