Introduction to Color Theory Flashcards
A visual sensation.
Color
One layer of the retina contains receptors (2 types)
How the Eye Distinguishes Color
- Rods
- Cones
Types of Receptors (in the retina)
- Responsible for various degrees of light.
- Are specialized for visions in dim light.
Rods
- Are responsible for perception of color.
- Visual acuity-sharpness of vision
- Are stimulated only by bright light.
- Cannot see color by dim light.
Cones
Is a highly personal experience. Influenced by:
- Past experience or association
- Asthetic preference
- Eye fatigue
- Visual acuity-sharpness of vision
- Color blindness
Perception of Color
The total or partial inability to distinguish and recognize colors.
Color Blindness
- Responds to red light (Roy)
- Responds to green light (G)
- Responds to blue light (Biv)
3 Kinds of Cones contained in the Retina
Different combinations of stimulus to the cones produce different colors.
Just as a Painter Mixes Colors
- Total
- Partial
Types of Color Blindness
No color perception. (Uncommon)
- Can only distinguish different shades of white to black.
- Missing all 3 types of cones
Total Color Blindness
Limited color percepton. (More common).
- Most common is red-green
- The cones most receptive to red or green light are missing.
- Can’t distinguish between red or green.
Partial Color Blindness
- A congenital condition
- Affects males more frequently than females.
Inheritance of Color Blindness
Tastefulness in funeral related activities.
- Color mixing
- Color selection and arrangement
Knowledge of the Principals of Color
- Paint mixing
- Room harmonies
- Flower arrangements
- Funeral setting
- Colored lighting
- Landscaping
- Clothing and casket interior harmony
- Cosmetology
- Display room
- Psychology
- Web-site design
- Funeral illumination
Utilizing Color
Proper lighting to use when viewing the deceased.
- Funeral home
- Church or other public building
- Lying in state
- Gravesite
Funeral Illumination
- Were made up of arbitrary standards by the artists.
- Color does not appear the same to all people.
- There were many rationalizations, but no agreements.
Early Theories of Color
- Argued the need for uniformity
- Sought to establish standards and ways to identify color.
Arrival of the Scientific Age- 17th Century Scientists
Discovered dispersion and the spectrum by experimenting in 1666.
Sir Isaac Newton
In a darkened room a small slit was made in the window shade to allow a beam of sunlight to pass through a prism which bent into a band of pure colors identified as the spectrum.
Newton’s Experiment
Breaking up white light (sunlight) into its many colors.
- accomplished by using a prism
Dispersion
Colors of the rainbow.
- Colors of Roy G Biv
- Pure colors that always appear in the same order.
Spectrum
Primary colors of light and are also the three types of cones in the eye.
Initials R.G.B.
Became the original “Scientific standard of color.”
The Spectrum
- Red
- Orange
- Yellow
- Green
- Blue
- Indigo
- Violet
Order of Colors in the Spectrum
Were able to measure the wavelengths of the visible spectrum in fine units called microns.
Physicists of Later Years
Fine units of the wavelengths of the visible spectrum.
Microns
Different colors have different ____ _____.
Wave Lengths
Has a long wave length, beyond this it goes into the invisible infra-red waves of heat.
Red
Has a short wave length, beyond this it goes onto the invisible ultra-violet rays.
Violet
Was eliminated from the spectrum because of its closness to blue and violet.
Newton’s Indigo
- An object’s color is identified by the wave lengths of light it reflects.
- The other rays are absorbed and converted into heat rays.
- All objects absorb and reflect some light.
Absorption - Reflection
- Reflect all colors in white light equally.
- There is a small amount of absorption.
- Reflected rays are not as vivid as light.
Absorption-Reflection: White Object
- Absorbs all colors
- Only a small amount of reflection
- Object is not as dark as the absence of light
Absorption-Reflection: Black Object
The principals of light and pigment are ______.
Different
The combination of all colors.
Light (White Light- Sunlight)
The absence of all colors.
Light- Black
The combination of all colors.
Pigment: Black
Involves combining of wave lengths.
White Light
Deals with the subtraction of wave lengths.
Pigmentary Mixtures
- Chromatic
- Achromatic
Types of Color
Colors comparable to the colors of the spectrum plus those produced by their mixtures.
Chromatic
Colors not appearing on the visible spectrum.
- Neutral colors: white, black, and gray.
Achromatic
