How to Fix light change when spawning my objects?

Hello! I am dealing with a small issue. I am making a 2D platformer game like flappy bird. When I am entering the game and spawn my logs(objects) they are changing color from darker to lighter ones. I have a parent object and child objects of this parent object those tree logs and a gem. I have also attached light components to them to change the color for them. Why this is happening?

I can’t see the prefab, so this is a guess, but I believe the light from each of the logs illuminates all of the logs. If you are using a directional light, that would be the cause. You may only need one for the entire scene.
