BASIC ELEMENTS OF PLASTIC EXPRESSION
Constitute a language with its own specific rules and allows the author to convey ideas, feelings or sensations.
- THE POINT
Most simple and small.
Indicates position.
Visual Effects: Concentration: cluster points
Dispersal: distance between points
Attraction visual:indication of place
Varying shape, size and color can express spatial depth and volume.
- LINE
Is defined as a point in motion. Has position and direction in space. One of its main functions is to delineate contours of the forms.
Structural characteristics: shape, thickness, color and texture depending on the technique and its use.
Rating:
according to the structure: Simple - with a single stroke
Compound – Broken: fragments of lines
Undulating; fragments of curved lines
Mixed: combination of both
according to the expressive value: vertical movement up and down
Horizontal: stability and calm
Oblique: instability and movement
- THE PLANE
Two-dimensional surface length and width which has position and direction in space.
Limited in space leads to the flat shapes.
Classification of flat shapes: Geométricas - mathematics
Organic - natural and dynamic
The binding of various flat shapes leads to the three dimensions, volume, adding to the previous depth.
Receives the action of the other elements on the great power of expression.
- TEXTURE
Quality of surface material due to the structure of the object and producing different visual and tactile sensations. Attached great expressiveness.
Classification: According to the source: Natural - in nature
Artificial - man made
According to the sense of perception: Touch
Visual
COLOR
Element capable of emitting plastic language sensations. You can only perceive light, the object absorbs all the shortwave except that matches its tone, which reflects that.


PRIMARY COLORS (1): basic YELLOW, CYAN, MAGENTA
SECONDARY COLOR (1 + 1) binary mixture of two primary
TERTIARY COLORS (2 + 1) primary plus secondary
COLORS QUATERNARY (2 + 2): two secondary
- PIGMENT COLOR: MIX SUBTRACTIVE: light subtraction, the result is black
- LIGHT COLORS: MIXED ADDITIVE: great light, the result is white
- CHROMATIC CIRCLE

Sort the colors and identifies their relationships, so that, according to the divisions, organized the first primary among these secondary, tertiary ... and two-faced in the two complementary.
Isaac Newton studied the decomposition of light and colors in 7 orders with respect to the rainbow.


- QUALITIES OF COLOR

TONE - hue or tint of each color
VALUE - lightness, clarity grade (high value) or dark (low)
SATURATION - purity, vividness or intensity. The pure colors have a maximum degree of saturation.
- CHROMATIC RANGES (may TONE, VALUE and / or saturation)

COLD: is the coldest color cyan, from green to violet
WARM: magenta hue from green to yellow
ACHROMATIC: between white and black

TECHNIQUES AND MATERIALS
METHODS OF PROCUREMENT OF TEXTURES
TACTILE TEXTURES. THREE DIMENSIONS
- SUBSTRACTION: Removing material
- ADDED: material is added
- PRINT: Leaving a mark on a material
VISUAL TEXTURE. GRAPHICAL. TWO DIMENSIONS
- WIPE (Frottage)
- RASP (grattage)
- DRIBBLE (Dripping)
PREPARATION OF CHROMATIC CIRCLE
COMPLEMENTARY
1 PRIMARY
2 SECONDARY
