Mainly regarding your war sounds app. If you insist on putting the nuclear trefoil (propeller) on your app, please at least use the correct colors. They are magenta for the trefoil and any text such as "radioactive materials" against a yellow background.
When I see what you're using, probably taken from somewhere else, it infers to me a certain level of ignorance.

So.. bast use the black color for the trefoil, and yellow background?
