The tint is a color on which some fancy visual effects (glossy reflections and so on) is applied. IOS applies them to app icons, tab bars, navigation bars and many other things. I think it would be wrong for you to make any assumptions as to what the local color for a given pixel is for a given tint, given these visual effects vary from UIElement to UIElement and probably from one OS version to another.
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.
