The colours are beautiful. There are several of them. But their combinations are even more beautiful. There are millions of them. You can limit yourself to black and white and watch your lifetime a black and white movie. But it’s better to add more colours and see the world in all its magnificence. And even better, mix the colours in your own discretion and get a complete unique result. As a result of mixing two people there is a completely new man and from the mixing of two colours there is a new tint. At the same time, the net species are doomed to extinction. Mixing is necessary for a progress, because the movement forwards stops soon without the influence of fresh blood. The great mixing is the initiator of life and the way to make it interesting.
