1. Color and the Color Wheel

2. Two ways to view color
1. Objectively: laws of chemistry, physics, and physiology
2. Subjectively: psychology
The perception of color means different things to different people

3. Types of color to be discussed
1. Local- natural. Reproduces colors seen in daylight
2. Optical- hues seen in light that is not daylight.
3. Arbitrary- emotional. Artist’s feelings or interpretations

4. Local
Arbitrary
Optical

5. Color Terminology Hue: Intensity or Chroma: Another term for color
The name that we give it.
Intensity or Chroma:
The brightness or dullness of a hue. A Hue can be dulled by adding its compliment or adding gray

6. Value:
The lightness or darkness of a hue in relation to black and white
Tint: a hue with white added
Shade: a hue with black added
Tone: A hue with gray (both black and white) added
Pure Hues vary in value.
Yellow is lighter than viloet.
Needs to adjusted with black/white to be equal in value

8. Sources of Color Colored Pigments or Dyestuffs
Natural compounds in the earth
like plants, minerals, or animals.
Artificial chemicals or compounds.

9. Sources of Color Spectral Light
Colored light that comes from nature.
Spectral colors are colored light bands known as the visible energy spectrum.
Spectral colors appear as the colors of the rainbow.

10. How We See Color Subtractive color theory:
1.) Light hits a colored object.
2.) All of the spectral wave bands are absorbed or subtracted except the hues that are painted, pigmented, or dyed.
3.) The remaining waves enter our eyes where the brain deciphers them.

11. Newton: wavelength

13. How We See Color Metamerism
The apparent change in color from one light to another.
True color is best viewed under full spectrum light (AKA natural daylight).
Color is best viewed in the setting in which it will be used.

15. How We See Color
Colors placed very near one another are visually mixed by a process known as subtractive or optical color mixing.
The human eye can potentially decipher over 10 million colors.

17. The Pigment Wheel Mixing based on subtractive color. Primary colors:
Red, Yellow, Blue
Secondary colors:
Orange Green Violet
Tertiary colors:
RO, YO, YG, BG, BV, RV

18. The Standard Color Wheel
Warm colors: red, yellow, orange.
Cool colors: blue, green, violet.
Neutral colors (A-chromatic): black, white, gray
Colors with no identifiable hue.
Neutralized colors: beige, brown, taupe, cream, ivory, off-black
Colors that fall midway between the warm and cool color groups

20. The Process Wheel Primary- Yellow, Magenta, Cyan Secondary- Blue Green
Often used in color printing, photography, and pigment (ink) manufacturing.
Primary- Yellow, Magenta, Cyan
Secondary-
Blue
Green
Red

21. The Light Wheel Additive Color- light rays and transparent color.
Primary- Red, Green, Blue
Secondary- Yellow, Cyan, Magenta

22. The Munsell Wheel
Partitive Color- based on the viewer’s reaction to colors when they are placed next to each other.

23. Primary- (5)
Yellow
Red
Green
Blue
Purple

24. “Tree”
Trunk
Branches
Neutrals

25. After Imaging-
an optical reaction that occurs after we stare intensely at a hue and then shift our eyes to a white surface.
the second hue is the after image.
Stare at Red and the after image is Blue-Green.

28. How We See Color Factors that affect color: Season and climate
Direction of light
North, South, East and West
Artificial Light

29. Laws of Color
Small amounts of high chroma are noticed and backgrounds are ignored
Color is more intense:
Placed next to its opposite
Places against a dull/ wht/gry/blk
Color is less intense:
Places next to neighbors
Colors of the same value

30. Visual Acuity and Deficiency
Visual Acuity- the ability to see or not see
color. Some of us have more than others.
Color deficiency or color blindness- the
inability to correctly distinguish value or pairs of complements from one another.
Red and green are the most common to be confused.
