COLOUR
It is difficult to describe the nature of colour with the means of numbers and words, because it won’t be complete. Nonetheless, enlarging the current concepts, we may accept the existence of three different levels of colour properties. None of these levels exists alone.
1st level:
The optical, Newton, rainbow, prismatic level that is the base also for the screen that shows you these words.
2nd level:
The physical, molecular, three-dimensional level holds the possibility to explain gold and black, which, of course, you wouldn’t find in a rainbow.
3rd level:
The metaphysical level of colour is able to express every thought or emotion of your mind and soul. Whereas the fact is objective, the effect on you is relative to your personal position of your mind and soul.
