A common misconception is that color refers only to a wavelength of light in the visual spectrum, from about 400 nanometers (violet) to about 700 nanometers (red). When an object reflects light of a given wavelength, we see that object as the corresponding color. So, for example, we might see a Braebum apple as red and a Granny Smith apple as green because they reflect light of different wavelengths. However, color is not merely a property of an external physical object but rather the result of an interaction among that object, the light that shines on it, and, finally but most significantly, the manner in which the human eye and brain make sense of the reflected light stimulus. Thus, the study of color can properly fall as much within the realm of psychology as that of physics.

Experience is one psychological factor that informs our perception of color. For example, a child eating by a campfire that emits a great deal of yellow light may believe that the melted Cheddar cheese served on white bread on a white paper plate is actually a white cheese like Swiss or Monterey jack. This occurs because the yellow light reflects off both the plate and the bread, which the child knows are white, and off the cheese, which the child isn't sure about. All the objects therefore appear to be the same color, and the child assumes that color is white. On the other hand, an adult with experience viewing things in firelight would intuitively adjust her perception to account for the yellow light and would not make the same mistake.

Color is also perceived differently depending on its context. The noted abstract painter Josef Albers produced an influential body of work based on this phenomenon, including his series Homage to the Square featuring nested squares of different colors. In one psychological experiment testing perception, the letter Xis presented against two colored backgrounds. Although the letter is identical each time it is presented, it appears olive green in one context and lavender in the other context. This effect is achieved when the X is given a low-saturation blue color, or gray-blue, and the backgrounds are also low-saturation colors with hues on either side of blue on the color wheel. Because blue falls between purple and green on the color wheel, a gray-blue X against a gray-purple background will look gray-green, or olive, and the same X against an olive background will look gray-purple, or lavender. In a similar manner, an intermediate color will look different against different primary color backdrops; teal, for instance, will look green against a blue background and blue against a green background.

Other subjective factors also influence the experience of color. These include cultural norms (Westerners most often name blue as their favorite color, whereas in China red is preferred) and simply what we learn about color. Consider that if a child learns that stop signs are "red," the child will call them "red." Another person in that society will also have learned to call stop signs "red." However, whether the two people are experiencing the same color is unknown since that experience exists only in the mind. Therefore, if one were to tell an interior designer that color is an immutable physical property of objects, one would meet with skepticism. Before placing the electric blue sofa in a client's living room, the designer considers the color of light the various light fixtures will emanate, the colors of the carpet and walls, and her client's feelings about electric blue, which after all may not even be the same color in the client's mind as it is in the designer's.
1) Which of the following statements best expresses the main idea of the passage?

A) Color is primarily a psychological construct, and therefore the study of physics is not relevant to an understanding of how color is perceived.
B) The phenomenon of color is a combined effect of the wavelength of light that shines on an object, the wavelength of light reflected by the object, and the human mind's perception of the light stimulus that comes to the eye.
C) Scientists have determined that although people may perceive color differently in different situations, color is an immutable characteristic of objects.
D) Creative professionals, such as artists and interior designers, view color significantly differently than do scientists.
E) To say that an object is a particular color is meaningless because color is a subjective perception influenced by experience, culture, and context and cannot therefore be ascertained to be a specific physical characteristic.

Show: :: OA
B



2) The author would be most likely to agree with which of the following ideas?

A) When attempting to achieve a particular aesthetic effect, a graphic designer should consider how the color used for the border of an advertisement will appear next to the color of the text.
B) A decorator working for a client in China would not purchase an electric blue sofa for that individual's living room, because blue is not a preferred color in China.
C) Companies designing packaging for their products should avoid using gray tones because these would cause different customers to see the colors differently, thereby rendering the brand message inconsistent.
D) Because red is a primary color, a wall should not be painted red if a sofa of an intermediate color will be placed against it, as the sofa's color may be distorted by its proximity to the wall.
E) Artists often explore the interaction of adjacent colors when juxtaposing different forms in the composition of their paintings.


Show: :: OA
A


Consider each of the choices separately and select all that apply.

3) According to the passage, which of the following accurately describes human perception of color?

A) A low-saturation color against a low-saturation background of an adjacent hue on the color wheel will appear a similar shade as the other adjacent hue.
B) An intermediate color against a background that is one of the intermediate color's components primary colors will be difficult to distinguish from that background.
C) Letters written in an intermediate color or in a low-saturation color are more likely to be misread by children than by adults.

Show: :: OA
A



4) The author mentions Josef Albers in paragraph 3 in order to

A) argue that artists are aware of how humans perceive color and use this phenomenon to enhance the impact of their work.
B) illustrate the idea that color is fundamentally a subjective, aesthetic phenomenon rather than a scientific one.
C) demonstrate that a child would probably see a painting in the Homage to the Square series differently than would an adult.
D) explain that humans perceive the color of regular shapes, such as squares, differently than they perceive the color of less regular shapes, such as food on a plate or a letter of the alphabet.
E) provide an example that reinforces the importance of the concept that color is a subjective experience manufactured in part within the human mind.

E



It took me 8:47 to read this passage and I only got the final question correct. I've tried the various techniques and I'm crestfallen.

it is almost 3 times more the time you should have for reading such passage.

This means only one thing: you are not comfortable that much.

What is your level of standard English ?? is it good ??

Because it is a confusion option: it melts the low saturation which is NOT mentioned in the 2nd paragraph where is the only portion of the passage in which there is underlined the difference between an adult and a child.

Now is more clear ?' it talks of two different things at the same time

Hi Carcass
Can you please explain first two. For the first one I am confused between B and E and for the second one between A and D.
Thanks for your help.

I do not think there is any doubt that is B the main idea

For the second, A is the best answer among the 5 but it is not the top-notch

I would say is the less bad. A talks about sideline but in the passage we do have background

It is not properly the same

D) Because red is a primary color,

Never mentioned primary color in the passage

Hi Carcass

First one is clear. For the second one, in the third paragraph last line they have mentioned about primary colour and intermediate colour so I am not sure why D is wrong. It might have something to do with proximity.

I will explain you better

in D we do have

Because red is a primary color, a wall should not be painted red if a sofa of an intermediate color will be placed against it, as the sofa's color may be distorted by its proximity to the wall.

red the sofa AND red the wall

In a similar manner, an intermediate color will look different against different primary color backdrops

In D is red on red

In the passage is a color on ANOTHER color and the first one is distorted

Hope now is clear

Took me around 11 min to solve. :-o

1) Which of the following statements best expresses the main idea of the passage?

A) Color is primarily a psychological construct, and therefore the study of physics is not relevant to an understanding of how color is perceived. - out of scope.
B) The phenomenon of color is a combined effect of the wavelength of light that shines on an object, the wavelength of light reflected by the object, and the human mind's perception of the light stimulus that comes to the eye. - That's overall the main idea.
C) Scientists have determined that although people may perceive color differently in different situations, color is an immutable characteristic of objects. - Too Specific. Out of scope
D) Creative professionals, such as artists and interior designers, view color significantly differently than do scientists. - Totally out of scope
E) To say that an object is a particular color is meaningless because color is a subjective perception influenced by experience, culture, and context and cannot therefore be ascertained to be a specific physical characteristic. - Author never said about meaningless. Rather he gave different points of view.

2) The author would be most likely to agree with which of the following ideas? (This is an inference question)

A) When attempting to achieve a particular aesthetic effect, a graphic designer should consider how the color used for the border of an advertisement will appear next to the color of the text. That's the overall idea of 2nd paragraph.
B) A decorator working for a client in China would not purchase an electric blue sofa for that individual's living room, because blue is not a preferred color in China. - out of scope. Passage does not says that Blue is not preferred in China.
C) Companies designing packaging for their products should avoid using gray tones because these would cause different customers to see the colors differently, thereby rendering the brand message inconsistent. - Not gray but blue. Stated in 3rd para
D) Because red is a primary color, a wall should not be painted red if a sofa of an intermediate color will be placed against it, as the sofa's color may be distorted by its proximity to the wall. - Not red but blue
E) Artists often explore the interaction of adjacent colors when juxtaposing different forms in the composition of their paintings. - Only one example is stated. It is not used usually.

3) According to the passage, which of the following accurately describes human perception of color? (This is a Detail type question)

A) A low-saturation color against a low-saturation background of an adjacent hue on the color wheel will appear a similar shade as the other adjacent hue. True.

Although the letter is identical each time it is presented, it appears olive green in one context and lavender in the other context. This effect is achieved when the X is given a low-saturation blue color, or gray-blue, and the backgrounds are also low-saturation colors with hues on either side of blue on the color wheel.

B) An intermediate color against a background that is one of the intermediate color's components primary colors will be difficult to distinguish from that background. - opposite.
C) Letters written in an intermediate color or in a low-saturation color are more likely to be misread by children than by adults. - Inconsistent. Children are stated in 2nd para whereas intermediate color is stated in 3rd para.

4) The author mentions Josef Albers in paragraph 3 in order to (This is a function question)

A) argue that artists are aware of how humans perceive color and use this phenomenon to enhance the impact of their work.
B) illustrate the idea that color is fundamentally a subjective, aesthetic phenomenon rather than a scientific one. - too general and not the function.
C) demonstrate that a child would probably see a painting in the Homage to the Square series differently than would an adult. - Inconsistent as child example is given in 2nd para
D) explain that humans perceive the color of regular shapes, such as squares, differently than they perceive the color of less regular shapes, such as food on a plate or a letter of the alphabet. - out of scope.
E) provide an example that reinforces the importance of the concept that color is a subjective experience manufactured in part within the human mind. True. Later that painting example was given.
