CH. 1 Nature of Color Flashcards
What’s Color?
Color is a uniquely human experience.
Aspects of Color
Physical, psychological, and chemical
PRIMARY COLORS OF LIGHT
- Red, green and blue (RGB)
- Primary Colors of light, esential hues or primary hues
- This are the components of all other hues
- Like Prime numbers this can’t be broken down
- Different from traditional painting primaries: red, yellow, blue.
ADDITIVE COLOR SYSTEM
The basis for all other color systems.
- Forming different colors, additive primaries wavelenghts are reflected or added together
- The seconrary hues form the primaries of process color.
COLOR PERCEPTION
Color is a uniquely human experience
HOW DO WE RECEIVE LIGHT INFORMATION TO SEE A COLOR?
Through two different types of color recepetors cells.
Rod cells: Light/Dark (Value)
Cone cells: Selectively respond to specific colors.
COLOR PERCEPTION FACTORS
Amount and quality of light on colored surfaces
Visual Health
Surface quality of the colored object
Source of the color (reflective, transparent, atmospheric, iridescent)
Color relationships (surroundings: lighting, shadows, highlights)
SUBTRACTIVE COLOR SYSTEM
Opaque surfaces that reflect light
Surface colors
Physical colors of pigments, inks or dies.
Describes the way light reflects from or absorbs into surfaces
In mixutres of paints or dyes, subtractive colors lose intensity as light wavelenghts are decreased or subtracted
SUBTRACTIVE COLORS
Pigment “Primaries”: Red, Yellow, Blue (RYB)
Process Primaries: RGB Secondaries (or Additives Secondary): cyan, magenta, yellow (CMY)
Pigment “Secondaries”: Green, orange, purple
ADDITIVE ⇔ SUBTRACTIVE COLORS
Is a clear inverse relationship
COMPLEMENTARY COLORS
Any two colors Opposite in the color wheel
Opposites = complements
Located directly across from each other on the color circle
Complete each other in a type of color balance
COMPLEMENTARY PAIRS
Subtractive System
Red ⇔ Green
Yellow ⇔ Purple
Blue ⇔ Orange
Additive System
Red ⇔ Cyan
Green ⇔ Magenta
Blue ⇔ Yellow
LOCAL AND RELATIVE COLOR
Color interaction
The general color of an object under normal lighting (daylight or white light) conditions.
Simple method of color perception and interpretation
Colors are perceived in context
It is based on comparison and contrast
Johnn Wolfgang von Goethe
(1749-1832)
Developed a color theory based on subtractive (pigments and surface color) perception.
