Color Theory and Symbolism Questions

Multiple choice

A man with colour blindness will see red as ____.

  1. yellow

  2. blue

  3. green

  4. violet
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The most common form of color blindness is red-green color blindness, where red is perceived as yellow. People with this condition have difficulty distinguishing between red and green, often seeing red as a yellowish-brown shade. This is due to missing or defective red-sensing cones in the retina.

Multiple choice

If there is no sun, the colour of the sky would be

  1. blue

  2. black

  3. red

  4. grey
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The blue color of the sky is caused by Rayleigh scattering of sunlight by atmospheric particles. Without the sun, there would be no light source to scatter, making the sky appear black (dark) as in space. The other colors mentioned require sunlight to be visible.

Multiple choice

Three colours of chart papers: green, red and blue have to arranged in such a way that all the chart papers are stored colourwise and height of each bundle is the same. The number of green chart papers is 96, of red chart papers is 240 and of blue chart papers is 336. Thickness of each chart paper is the same. Determine the number of bundles of green, red and blue, respectively.

  1. 35, 14, 10

  2. 48, 48, 48

  3. 2, 5, 7

  4. 32, 80, 112
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

In order to arrange chart papers as required we have to find
 
the largest number that divides 96,240 and 336.Clearly such
number is their H.C. F.
96  = 2 x 2 x 2 x 2 x 2 x 3
 
240 = 2 x 2 x 2 x 2 x 3 x 5
 
336 = 2 x 2 x 2 x 2 x 3 x 7
 
H.C.F. = 2 x 2 x 2 x 2 x 3 = 48
 
 
Hence there must be 48 chart papers in each bundle
 
 Number of green chart paper bundles = 96/48 = 2

Number of red chart paper bundles = 240/48 = 5 Number of blue chart paper bundles = 336/48 = 7

 

Multiple choice

Colours at the extreme ends of a rainbow are

  1. V & R

  2. V & B

  3. V & G

  4. V & Y
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The rainbow spectrum follows the order ROYGBIV - Red, Orange, Yellow, Green, Blue, Indigo, Violet. Violet is at one extreme end (shortest wavelength, highest frequency) and Red is at the other extreme end (longest wavelength, lowest frequency). Therefore, V & R represents the extreme ends.

Multiple choice

Which colour on an airspeed indicator depicts the flap operating range ?

  1. Green

  2. White

  3. Black

  4. Red
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

The white arc on an airspeed indicator marks the flap operating range, showing the speeds at which flaps may be safely extended. The lower end indicates the speed at which flaps can be fully extended, while the upper end shows the maximum speed with flaps deployed. This range is critical for safe flap operation during approach and landing.

Multiple choice

Which colur depicts the caution speed range?

  1. Yellow

  2. Green

  3. Red

  4. White
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The yellow arc (caution range) on an airspeed indicator indicates speeds where the aircraft may be operated only in smooth air conditions. This range extends from the normal operating limit (end of green arc) to the never-exceed speed (red line). Operations in this range require caution as turbulence or abrupt control movements could cause structural damage.

Multiple choice

Which colour depicts the never exceed speed?

  1. Green

  2. White

  3. Red

  4. Amber
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The red radial line on an airspeed indicator marks the never-exceed speed (Vne), which is the maximum speed the aircraft structure can withstand. Exceeding this speed, even momentarily, risks catastrophic structural failure. Vne is determined during flight testing and includes a safety margin below the actual speed at which the aircraft would break apart.

Multiple choice

Which colour depicts the normal operating range of an airplane?

  1. Green

  2. White

  3. Red

  4. Yellow
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The green arc on an airspeed indicator depicts the normal operating range, which includes all safe operating speeds from maximum flap extended speed to normal maximum speed. Within this range, all normal flight maneuvers can be conducted safely. The green arc provides pilots with a clear visual reference for routine operations during all phases of flight.

Multiple choice

The colours and images which appear same on all displays and browsers, are

  1. web safe colours

  2. web colours

  3. true colours

  4. high colours
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Web safe colors are a specific palette of 216 colors that display consistently across different browsers, operating systems, and monitors. This was particularly important in early web design when display capabilities varied significantly.

Multiple choice

Which of the following results in the red colour of the rising and the setting sun, and the blue colour of the sky?

  1. The insolation received by the surface of the Earth

  2. The absorption of light within the atmosphere

  3. The scattering of light within the atmosphere

  4. The absorption of long wave solar radiation within the troposphere

  5. The transfer of shortwave solar radiation through the air waves
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

The red colour of the rising and the setting sun, and the blue colour of the sky are the result of scattering of light within the atmosphere. This is the correct answer choice.
