CHP 7: COLOR THEORY Flashcards
WHAT IS LIGHT?
A FORM OF ELECTROMAGNETIC RADIATION THAT ACTS UPON THE RETINA OF THE EYE TO MAKE SIGHT POSSIBLE
WHAT IS SPECTRUM?
- AKA OG STANDARD OF COLOR
- A VISIBLE BAND
- THE PROGRESSIVE ARRANGEMENT OF COLORS (ROYGBIV) SEEN WHEN A BEAM OF LIGHT IS BROKEN DOWN INTO ITS COMPONENT COLORS
WHAT IS ABSORPTION?
- THE PROCESS OF TAKING IN
- WHEN COLORED OBJECTS ABSORB CERTAIN RAYS OF LIGHT AND REFLECT OTHER RAYS, GIVING THE OBJECT A RECOGNIZABLE COLOR
- EX: A LEAF, THE LEAF ABSORBS ALL COLORS BUT REFLECTS GREEN GIVING IT THE DISTINGUISHED COLOR
WHAT IS REFLECTION?
- THE RETURN OF LIGHT WAVES FROM THE SURFACES
- EX: LADYBUG
WHAT IS PIGMENT THEORY?
-A SYSTEM WHICH THEORIZES THAT ALL VISIBLE COLORS ORIGINATE FROM 3 PRIMARY COLORS
- BLUE, RED, YELLOW = PRIMARY COLORS
WHAT IS HUE?
- MEANS COLOR
- REFERS TO THE ORIGIN OF THE COLOR WE SEE
- THE PROPERTY OF A COLOR BY WHICH IT IS DISTINGUISHED FROM THE OTHER COLORS
WHAT IS VALUE?
LIGHTNESS OR DARKNESS OF A HUE (COLOR)
WHAT IS CHROMA?
- AKA SATURATION / INTENSITY
- DESCRIBES HOW BRILLIANT OR SUBDUED THE COLOR LOOKS
- EX: A LEMON HAS MORE CHROMA (BRIGHTER) THAN A BANANA
WHAT ARE THE CLASSES OF HUE?
- PRIMARY HUE
- SECONDARY HUE
- INTERMEDIATE HUE
- WARM HUE
- COOL HUE
WHAT IS PRIMARY HUE?
- ONE OF THE 3 PIGMENTARY HUES (R, YW, BL)
- CAN BE COMBINED TO MAKE ALL OTHER HUES
- CAN NOT BE PRODUCED BY ANY OTHER MIXTURE OF COLORS
WHAT IS SECONDARY HUE?
- OG, GR, PR
-MIX OF EQUAL PARTS OF 2 PRIMARY HUES
- EX: 50% YELLOW + 50% RED = OG
WHAT IS AN INTERMEDIATE HUE?
- PRIMARY HUE + ADJACENT SECONDAY = INTERMEDIATE
- PRIMARY COLOR MAKE UP FIRST PART OF THE NAME
- EX: RED ORANGE = RED + ORANGE
WHAT IS A WARM HUE?
- CONSISTS OF RED, ORANGE, YELLO,W AND ANY OTHER COLOR THEY PREDOMINATE
- MAKES OBJECTS APPEAR CLOSER AND LARGER
- REFLECTS WARMTH
- CHARACTERIZED BY LONG WAVE LENGTHS
WHAT ARE COOL HUES?
- CONSISTS OF BLUE, GREEN, PURPLE, OR ANY INTERMEDIATE PIGMENTARY HUE THEY PREDOMINATE
- AKA A RECEDING HUE; CREATES THE ILLUSION OF DISTANCE FROM THE OBSERVER
- CHARACTERIZED BY SHORT WAVE LENGTHS
3 MAIN WAYS TO CHANGE THE VALUE OF HUE
- TINT
- SHADE
- TONE
WHAT IS SHADE?
HUE MIXED W/ VARIOUS AMOUNTS OF BLACK
WHAT IS TONE?
- PURE COLOR MIXED WITH PURE GRAY (equal parts of black and white)
- GRAY DULLS INTENSITY
WHAT IS TINT?
- VARIOUS QUANTITIES OF WHITE ARE MIXED IN
TYPES OF COLOR HARMONY?
- MONOCHROMATIC
- ANALOGOUS
- COMPLEMENTARY
- JUXTAPOSITION
WHAT IS MONOCHROMATIC?
- ALL VARIETIES (tint, shade, tone) OF A SINGLE HUE
- RANGES BETWEEN LIGHTER AND DARKER VERSIONS OF THE BASE OF THE HUE
WHAT IS ANALOGOUS?
- GROUP OF 3 COLORS NEXT TO EACH OTHER ON THE COLOR WHEEL
WHAT IS COMPLEMENTARY
- PAIR OF COLORS THAT CANCEL EACH OTHER OUT WHEN MIXED / COMBINED
- PRODUCED GRAY
WHAT IS A JUXTAPOSITION?
-TWO HUES PLACED TOGETHER AND VIEWED SIMULTANEOUSLY, INFLUENCING THE APPEARANCE OF THE OTHER
- GREATER DISTANCE BETWEEN HUES ON A COLOR WHEEL = GREATER CONTRAST
- COMPLEMENTARY HUES = ENRICH E/O
-NON COMPLEMENTARY = DULL E/O
TYPES OF LIGHT
- INCANDESCENT
- FLUORESCENT
- LED
WHAT IS INCANDESCENT?
- ILLUMINATION RESULTING FROM A HEATED FILAMENT
-EX: EDISON LIGHT
WHAT IS FLOURESCENT LIGHTING?
- ILLUMINATION PRODUCED BY A TUBULAR ELECTRIC DISCHARGE LAMP
- PHOSPHORUS COATING ON THE INSIDE OF THE TUBE GIVES IT THE FLOURESCENCE
WHAT IS LED?
- LIGHT EMITTING DIODE
-SEMICONDUCTOR DEVICE THAT CONVERTS ELECTRICITY INTO LIGHT
-KNOWN FOR NIGHT ENERGY SAVINGS AND LONG LASTING DURABILITY
WAYS OF MIXING COLORED ILLUMINATION
- ADDITIVE METHOD
- SUBTRACTIVE METHOD
WHAT IS THE ADDITIVE METHOD?
- PROCESS OF MIXING COLORED LIGHTS ON A SURFACE WHERE THE WAVELENGTHS COMBINE
- ADDING 2+ COLORED LIGHTS TOGETHER TO CREATE ANOTHER
WHAT IS THE SUBTRACITVE METHOD?
- DIMINISHING THE WAVELENGTHS BY SUPERIMPOSING 2+ COLOR TRANSPERANCIES OVER THE SAME LIGHT SOURCE
- LIGHT IS GRADUALLY REDUCED BY ABSORPTION
