P1 – In visual perception, a colour is almost never seen as it really is – as it physically is.
This fact makes colour the most relative medium in art.
P2 – Just as the knowledge of acoustics does not make one musical – neither on the productive nor on the appreciative side – so no colour system by itself can develop one’s sensitivity for colour.
This is parallel to the recognition that no theory of composition by itself leads to the production of music, or art.
P3 – Colour recollection – visual memory
If one says “Red” (the name of a colour) and there are 50 people listening,
It can be expected that there will be 50 reds in their minds.
And one can be sure that all these reds will be very different.
Even when a certain colour is specified which all listeners have seen innumerable times – such as the red of the Coca-Cola signs which is the same red all over the country – they will still think of many different reds.
First, it is hard, if not impossible, to remember distinct colours.
This underscores the important fact that the visual memory is very poor in comparison with our auditory memory. Often the latter is able to repeat a melody heard only once or twice.
Second, the nomenclature [a system of names] of colour is most inadequate.
Though there are innumerable colours – shades and tones – in daily vocabulary, there are only about 30 colour names.
P 4 Colour reading and contexture
In writing, a knowledge of spelling has nothing to do with an understanding of poetry.
Equally, a factual identification of colours within a given painting has nothing to do with a sensitive seeing
Nor with an understanding of the colour action within the painting.
Our concern is the interaction of colour: that is, seeing
What happens between colours
We are able to hear a single tone.
But we almost never (that is, without special devices) see a single colour unconnected and unrelated to other colours.
Colours present themselves in continuous flux, constantly related to changing neighbours and changing conditions.
As a consequence, this proves for the reading of colour what Kandinsky often demanded for the reading of art:
What counts is not the what but the how.
P 45 Film colour and volume colour – two natural effects
Usually, we think of an apple as being red.
This is not the same red as that of a cherry or tomato.
A lemon is yellow and an orange is like its name.
Bricks vary from beige to yellow to orange,
And from ochre to brown to deep violet.
Foliage appears in innumerable shades of green.
In all these cases the colours names are surface colours.
For a very different colour effect compare the coffee in a cup with the coffee in the stem of a percolator or with the coffee in a silex glass.
It is easy to discover that, although all 3 containers hold the same coffee, the containers show this coffee in 3 different browns:
Lightest in the stem, darker in the cup, darkest in the silex glass.
