Exam 5: Perceiving Color

If you are shown a spot of light,is it possible to perceive whether you are viewing a single wavelength of light as opposed to multiple wavelengths superimposed on the same location? Explain why or why not.

Dichromacy refers to the condition where the person

In order for color constancy to occur

For a person who has only one type of cone,changes in the of light are indistinguish- able from changes in the of light.

Color matching experiments support the Young-Helmholtz theory of color vision

For a person with only two types of cones (say M-cones and L-cones),a metameric color match could

When a source emits light that consists of a wide range of different wavelengths it

One possible explanation for color constancy is called ,and it argues that .

Hurvich and Jameson's (1957)study of hue cancellation showed that there was no unique

For a person with only one type of cone (say M-cones),a metameric color match could

Your five-year-old daughter has her heart set on having her room painted a bright shade of green.What possible drawback,as far as the color goes,is there in simply mixing your leftover supply of blue and yellow paint for this job? (Assume the paints are in perfect condition. )

Additive color mixture would entail mixing

The color circle includes ,while the color solid includes .

Digital video displays

People with normal color vision require monochromatic comparison light(s)to match any monochromatic test light.

In the following diagram

The absolute sensitivity of S-cones is

With additive color mixing,an example of complementary colors would be

A person who suffers from tritanopia

Mixing blue and yellow paint gives the appearance of green because
