Any colour would work but be sure to incorporate touches of that same colour throughout the room. Like if it's red, then have a large red bowl with white seashells in it and a red throw or toss pillows in red, too. You don't want to have the rug be the only thing that's a brighter colour.
But pick a colour you really love.

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.
