The dark color is associated with the mysterious dark void of the unseen unknown similar to the human ignorance and fear to palisade in one's own convictions to reject the Truth which in religious doctrines was considered evil. Black color was used in pagan rituals/witchcraft to create fear experienced by ignorant people in unexplained phenomenons eg: lunar & solar eclipses-night etc. Biblical and many religious scripture have described evil as dark. Both oral & written literature have described evil as dark eg: Milton-'Paradise Lost Darkness is dispelled by light where humans visualize as Truth and associate it with knowledge and divine element.
The color white therefore is associated with purity & divinity These ideas are strongly culturally bound. Keep in mind phrases like "in the black", meaning doing ok with regard to money; not in debt (in the red). Also, in some cultures, white is the color of death.
Black is a strong and fashionable color. For women who can wear it, few colors are as stunning. Keep culturally bound assumptions in mind, and keep them in check.
There is nothing inherent in any color that indicates or suggests goodness or evil. Think of them and use them figuratively, but keep your wits about you.
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.
