The key here is matching. You will need to get a good size chip off the wall and take it to the local home center / paint shop to have it color matched. They will custom mix the paint for you so you can just paint it on and have it match.
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.
