So i’m trying to make a underground tunnel like thing and it is kinda a failure.
So the tunnel has been built but the colors are very bad.
Here are some photos.
(I know you can’t even understand that there are walls in the map)
As you can see the walls and floors are camouflaged and it is making problems while building and makes the tunnel poorly built and makes it confusing for the players.
How can I make them a bit brighter? 
Can anyone help?
Insert a part into the tunnel, then insert a point light into the part. Set the range and brightness properties higher.
Add some lighting via the method mentioned in the above comment here: Need help on building - #2 by VegetationBush
Maybe also try to add textures as well to make it more real-istic looking, some pipeline work maybe even?
Thank you for the solution 
Hope you have a nice day. 
Ok I will try to add some textures to make the map look realistic.
