Overview-Introduction to color-Visual variable-Psychoperspective space-The necessarity of number 3-System of color-Color-matter- Way of appearing of the color-Phenomenology of color
Ethymology of the word ‘color’:
1. warm/ emotion2. Chroma3. Celare = to hide4. Cloros (yellow-green)
Historical point of view about color:
- Color-idea by Cartesio- Color-useful by Berkley- Color-inuseful by Kant- Color-biocenotic by
Darwin
Introduction to color
8 Visual variable
4 variables of image
4 variables of separation
1. Dimension2. Value3. Trasparency4. Position
1. Direction2. Texture (tactile by sight)3. Hue (hue + value = color)4. Shape
Visual variable
Shape and howcan theybe assembled
Psychoperceptive space
Psychoperceptive Space. What is it?
It’s just like a window open to the world
Psychoperceptive Space
The space is defined through the psychoperceptive activity of the observer.
The space is not only physic. The perceptive space is metric free.
Nino Di Salvatore - Archetipo oggettivo verde e giallo - 1969
The psychoperceptive space is composed by:
a. Vectorial constances of the perception a1. Retinical image’s dimension a2. Axis of gravity’s parallelism a3. Chromatic gradient a4. Color focusing a5. Position in the visual field
b. Spatial forces b1. Shape b2. Dimension b3. Orientation b4. Optical weight b5. Latent lines (visual flow) b6. Interval
Task: Spatial expression
a.Vectorial constances of the perception
1.Retinical image’s dimension
2.Axis of gravity’s parallelism
3.Chromatic gradient4. Color focusing 5. Position in the visual
field

UN QUADRATO FERMO VICINO ALL’OSSERVATORE IN UNO SPAZIO TRIDIMENSIONALE CON TRE QUADRATI IN MOVIMENTO CHE SI ALLONTANANO
Which is the best way (color, dimension, position,..) to representthis situation?
..?..
This is the best solution!!
...because it uses at best the vectorial costances of the perception
b. Spatial forces
The spatial forces can manifest through:
1.Shape2.Dimension3.Orientation4.Optical weight5.Latent lines (visual flow)6.Interval
Putting a shape in a field is just like putting a stone in a pond
Every shape has an extention much bigger than its physical extension.
Spatial forces
1. Shape
Every shape has his own spatial forces

3D2D
Dimension is critical in generating 2D and 3D spaces.
2. Dimension
Vassily Kandinsky (1866 – 1944)
9 punti in ascesa
Static space Dynamic space
3. Orientation
Rodchenko, Russian
4. Optical weight
Everybody makes the same visual path to join the shapes in the visual field. This visual path is constituted by the latent lines. They are not real, they are generated psychoperceptively by the observers. Althought that they have the same value of the designed lines.
5. Latent lines
6. Interval

● Complementarity in the color
● Polarity in the space
Opposition in geometry
● Duality in the shape
..it’s can be defined as..
If I had only 1 color there will be no color. For a color to exist it has to be created something of different nature. Only in this way it can feel its existence.If I fix a color and then a black sheet, the color creates his complementary, its contrary. The two colors together form a unity. A color is really itself when near to its contrary. A color expresses at best its property when it is near its complementary color.
Complementarity in the color
Klee’s lessons
The balance between opposite colours is not grey Klee speaks of a pendolum.
- different hue- different lightness- PEN relative to the gravity, the weight- high contrast
- different hue- similar lightness- TEN relative to the tension- low contrast

The necessarity of the number 3
The passage from 1 to 2 can be seen as a passage from being to appearing. If I had only the 1 there will be no term of confront. If I had only 1-2 there will be a tautology. The number 3 establishes a principle of order. The number 3 is a structural necessity.

- CMY are the primary of the matter - Nearer to the black (K)
Subtractive color mixing
- CMY are the primary of the energy- Nearer the white (W)

Phenomenology of color
1. Trasparency
Conditions:a. The field should be divided in 4 parts, 2 for the figure and 2 for the background
b. Each of the 2 parts of the figure should be in contact with only 1 part of the background
c. The 2 parts of the figure should be perceived as an unity (Figural condition)
b. The succession of the colors of the figure should be related to that of the background (clearer figure on clearer background and viceversa)
2. Induction - Interraction
The same squared perimeter, but one time interaction and the other inductionCause: different disposition of the color in the perimeter
3. Marginal gradient
4. Color’s diffusion
5. Hermann’s grill
6. Munker White’s phenomenon
7. Teodorovic’s experience
