BASIC HAPPENING OF COLOUR.


When we "see" colour, it is a process involving 3 dimensions, namely Light, Surface(object) and Observer.
Every one of the 3 dimensions influence the eventual colour we "see".  I'm going to explain briefly but in a very simple way the working of all three dimensions, to make you aware of why colour is an absolute private experience where no one else will ever know what colour or tone you see. It is a subjective experience.
In the diagram you can see an illustrated process of seeing, namely 1 LIGHT RAYS (of the sun or any artificial light source)consisting out of 7 spectrum colours,  2 OBJECT(apple) and 3 OBSERVER(eye and brain).

COLOUR, A WAY OF LIFE

Image
C olour is and will always be a science    and one must be careful how and   where and for whom the colour is designed. We have to accept that no manufacturer of paint, interior decorator or magazine can decide and advice on the generalized influence and use of colours in the humane colour world, because we are dealing with a sense, vision, influenced by light, surface and observer. We “see” ( experience) colour through our sense, sight(eye) and that process is known as VISION . The lack of confidence in colour choices, is mainly caused by the commercial               exploitation of colour, because people accept their colour advice as scientific correct and do not realize that colour   use is more complicated than the   choosing of a beautiful colour! Colour may evoke associations with odour and taste , appear heavy or light , give   tactile      ...

 4  WHAT IS NECESSARY FOR COLOUR TO BE SEEN? Colour is the result of the combined influence of the "IN THERE " and " OUT THERE " events. WE refer to it as the 3D Colour Dimensions, namely LIGHT, OBSERVER and OBJECT . Colour does not exist in the physical sense. In every second of observation, the interaction of light , surface , and human perception create colours(Hue) anew. And because sensitivity to colour differs among individuals, each person's perception will be unique in some way, based on what he/she has just perceived and all that has been received before. Understanding the working of all three the Colour Dimensions, will make you realize why we cant all see colour the same. What is LIGHT ? Light is visible energy(Radiant Energy) that is emitted by a light source. A light source can be any one of a number of things: the SUN, and any artificial light source. The sun is the most important natural source of light, which contains all seven the spec...

COLOURS IN ROOMS, AN EXPERIENCE

Image
. Every room has its own reason for accepting or rejecting a colour. This is reason enough for us to have a room experience. Experience has proved to us that some of the colours we have chosen, seldom work the way we wanted, but we seldom admit it to our self. We mostly work with surface colours to create the mood of a space. But, room experience not only involves colour, but all the elements contained in its ensemble. We are not always aware of the fact that the architectural environment influences the human psyche beyond aesthetical impressions. No wonder it is wrongly assumed that as long as an architectural space is aesthetical pleasing, it satisfies the needs and function of the environment. Resulting in, the choosing of colours is done to compliment the environment, and the influence of the colour on the inhabitants is ignored. Colour experience, what does it actually means? To perceive colour, means to experience, to become consciously aware of. The process of colour ...
