Once upon a time, Nitrogen and Oxygen started discussing issues related to deceases and stuff.
It turned out that the word "insult" indicated making somebody being offended, which sometimes led to a blood stroke.
In other words, insulting may result in death. Elements understand this simple fact. What about other creatures, let's say alligators? By the way, chemical signaling has been found in the blood of the latter.
Finally, the elements started thinking what this fact could have to do with the phenomena of red being over black. Apparently, Kazimir Malevich would have been a good chemist. Furthermore, he might have preferred green, for instance.
However, elements stopped thinking about the whole issue on some reason. Perhaps, compromise is not for elements. They wouldn't go for it, even if it was arranged by Madonna, who always inspired them.
