Our observe color through the lens of our eye. It reflects the colors we see in our everyday life whether it’s in our home, our environment, in objects and people.
=================================================================
WHAT IS COLOR?
Color is the property of light, not of objects or liquids. (pg. 53)
The eye receives light of wavelength,
It reflects off objects transmitting through fluids.
White light is a reading lamp or the sun that is divided by a prism.
It is a rainbow color of red and purple that is called a spectral colors of wavelength
================================================================
HOW WE PERCEIVE COLOR
Basic Physiological factors
The lens of the eye focuses light on the light-sensitive cells of the retina which is a combination of cones and rods.
Rod and Cone are movement to the light in different ways
Cones need More light to fire than rod
One group is sensitive to the short waves that makes up blues
Second group responds to a medium waves of green
Third to a long wave of the red end of the spectrum
Basically the colors are mixture of wavelengths and the groups are action of bright lights. The cones fire its own signal that results in a high resolution image of color.
The rods do not respond equally across the color spectrum and are, for all practical purposes, colorblind.
Jump to action I gets dark
cones give up lack of adequate light
You don’t see color in dim light but things around you
Rod gives low illumination to deliver a strong signal for the brain to process. You see cones of fuzzy images that fires separately
Before the brain can make us see color, or adapt our vision to a certain level of darkness, the cones and rods must send their signals to neurons, which process the signals and code them into simpler ones. See 4.1 Color Perception
BASIC AESTHETIC PERCEPTION FACTORS
When we look at colored objects, we can detect three basic color sensations:
The color itself—red, green, or blue; the color strength—whether a red is deep and undiluted or looks faded and washed out; and how light or dark it appears to us.
These three basic color sensations we call color attributions. (pg 55)
Color attribute: hue: the Hue is a rainbow of different colors around us.
The hue helps you clarify colors
Colors of the spectrum are pure hues (
Most colors we see are impure (washed out)
Whole color is based on only four hues: Red, Yellow, Green and Blue
See color plates 2 and 3 next to page 54
CP2
(Sight Sound Motion)
All colors are computer or television screen created with only three hue colors from RGB which are: RED, YELLOW, GREEN and BLUE
The computer displays different single one of these color combinations you could recognize it and tell whether it was bluish, reddish, greenish, or yellowish, light or dark.
The Color Palette, See CP8 Color Models

Color attribute: Saturation, sometimes called chroma (a Greek name,) is a strength or purity of color. It is a highly saturated color looks rich; a color with low saturation looks wash out.
SEE COLOR PLATED 4, 5, and 6
COLOR ATTRIBUTE BRIGHTNESS: See Color Plate 7
GRAYSCALE
Black and white, or monochrome, video or film shows only achromatic colors which are various steps of brightness. These are steps are created by grayscale steps. There are different variations of gray ranging between white and black.
You can see a shadow not as uniformly dark but in various degrees of transparency.
It’s a light area that displays more of a differentiated bright area into an overexposed white area.
The video camera and a monitor deliver several measuring grayscale.
Video:
work with nine or 12 brightness, or grayscale
television white (a little off white) and television black (not pitch black)
Good Video camera delivers more brightness steps with HDTV
Computer graphic have a pixel that ranges 256, starting with black
254 shade of gray and ending with white
COLOR MODELS: These are all array of hues and degrees of saturation and brightness.
See color Plate 8
COMPATIBLE COLOR
Color videos are encoded so it can be received and reproduced by black and white television.
Colors have enough brightness contrast that will present a monochrome video screen in different shades of gray
Black and white video no longer exists only for industrial use and all movies produced in color
There are several reasons
Lightness and darkness elements gives picture its definition.
Black-and-white rendering produces a higher-resolution than a color one.
Monochrome scene has its very own aesthetic that is quite different from a colored one.
==============================================================
HOW WE MIX COLOR
Additive color mixing by shining, or adding, colored lights on top each other.
Subtracting color mixing by mixing paints or combining color filters
The basic colors are: See Color Plate 10
ADDITIVE COLOR MIXING
The primaries of additive mixing are Red, Green, and Blue. These are your additive primaries, or RGB.
Additive mixing with colored light:
Mixing red slide in one slide projector,
Green slide in a second
Blue one in third and overlapping them
partially on the screen
See Color Plate 11
Additive mixing in video:
See color plate 12
Inside the CRT (cathode ray tube) of a standard television, receiver have three primary colors (Red, Green and Blue Light) that signals activate electron guns and each shoots beams of color dots inside the television screen,
See color plate 13
(Sight Sound Motion)
See color plate 14
Complementary colors: See color plate 3
SUBTRACTIVE COLOR MIXING
Involves filtering out, or subtracting from white light all colors except the one it displays
See Color Plate 13
MIXED MIXING
See 4.2 on page 61

COLOR TEMPERATURE
- Our color perception are also influenced by the kind of light under which we experience them." (pg-62)
- "White Light"
-No light is ordinary pure or white
- For example, midday we see sunlight that has an extemly blush tinge during sunrise or sunset
- Measured by Kelvin degrees (K)
=================================================================
SURROUNDING COLORS
- The way we pervice color is influenced by surrounding colors
- Similar Colors
Ex. Someone wearing blue on a set
- Contrast Colors
- Contrast between foreground and background.
