I think that an earthy color scheme would be better than the creamy beige that is in there right now. A little darker shade or a more softer tone like a green or blue, would be better for sleeping at night than bright colors.
I would choose white. My imagination lets me change the color of my room, everyday.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
