Contrasts

As a child playing with colors rapidly, I noticed the harmony and beauty by juxtaposing contrasts. The most evident are black/white, dark/light, and warm and cold. But if you read the elements of colors by Johannes Itten, you'll see a lot more possibilities. In fact, everything is a question of contrasts. This allows us to take one's bearings, and life should be terribly monotonous without it. Its by differences our world becomes comprehensible. How should we appreciate silence if we don't know what a noisy environment is?
Humans always must be able to compare and have a scale of values. In films, paintings, and photography, its with differences that we can situate objects and persons in space by creating an illusion of relief or profundity.
What's true for Art is always true for Society. Why should we banish differences of culture, way of life, mentalities, traditions, religions, social levels, and so on? One of the most important rights of humans should be to be ourselves!
