The lightest shades of colors reflect the most light and would make the room look brighter. So white, then yellow, then a pale apricot etc. down to a pale lavender would all look brighter than medium versions of those same colors. Black, chocolate brown, navy or purple would reflect the least light so avoid dark colors.
Also invest in lighting for the room with a ceiling fixture and bedside lamps that allow for higher wattage bulbs for more light. Maybe a floor lamp in the darkest corner of the room, too.
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.
