Optical Color Test: Can You Pass? - Quiz

A good eyesight is something to be proud about. The eye uses light to achieve its function. And this is not a far cry in optical color assessment. If a viewer is able to perfectly sight two different colors placed side by side, then he is no sufferer of colour blindness. Do you know much about optics and colors?

Questions and Answers

1.

Which of the following is not a type of color blindness?
- A.
  
  Trichomacy
- B.
  
  Dichromacy
- C.
  
  Tritoponia
- D.
  
  Protanopia
Correct Answer
C. Tritoponia

Explanation
Tritoponia is not a type of color blindness. The correct term for this condition is tritanopia, which is the inability to perceive the color blue. Trichomacy refers to normal color vision, dichromacy is the presence of only two functioning cone cells for color vision, and protanopia is the absence of the red cone cells.

What part of the eye focuses the light?
- A.
  
  Iris
- B.
  
  Cornea
- C.
  
  Retina
- D.
  
  Lens
Correct Answer
D. Lens

Explanation
The lens is responsible for focusing light onto the retina. It is a transparent structure located behind the iris and the pupil. When light enters the eye, it passes through the cornea and then through the lens, which adjusts its shape to focus the light precisely onto the retina. This process allows for clear and sharp vision. The iris, on the other hand, controls the amount of light entering the eye by adjusting the size of the pupil. The retina is a layer of cells at the back of the eye that detects light and sends signals to the brain for visual processing.

What is a viewer most likely observe in the presence of black and white lines?
- A.
  
  Orange
- B.
  
  Indigo
- C.
  
  Pink
- D.
  
  Gray
Correct Answer
D. Gray

Explanation
In the presence of black and white lines, a viewer is most likely to observe the color gray. This is because black and white are both achromatic colors, meaning they have no hue. When these colors are combined, they create shades of gray. Therefore, gray is the most likely color that a viewer would observe in this situation.

What painting method involve the use of small dots?
- A.
  
  Dry brushing
- B.
  
  Shade
- C.
  
  Glazing
- D.
  
  Pointillism
Correct Answer
D. Pointillism

Explanation
Pointillism is a painting method that involves the use of small dots. It was developed by Georges Seurat and Paul Signac in the late 19th century. Instead of using brushstrokes, artists create images by applying small dots or strokes of pure color next to each other. When viewed from a distance, these dots blend together to create the illusion of different colors and shapes. Pointillism is known for its vibrant and luminous effects, and it is often associated with the Neo-Impressionist movement.

Which of these is not used in optical color mixing?
- A.
  
  Colored pencils
- B.
  
  Mallets
- C.
  
  Brush
- D.
  
  Pastel
Correct Answer
B. Mallets

Explanation
Mallets are not used in optical color mixing. Optical color mixing is a process where colors are mixed by overlapping or combining them optically, without actually physically mixing the pigments. It is commonly used in art and design, and tools such as colored pencils, brushes, and pastels are typically used to create optical color mixtures. However, mallets are not used in this process as they are primarily used for striking or pounding objects, not for creating color mixtures.

6.

What cell in the retina is responsible for color vision?
- A.
  
  Optic cell
- B.
  
  Rods
- C.
  
  Cornea cells
- D.
  
  Cones
Correct Answer
D. Cones

Explanation
Cones are the cells in the retina that are responsible for color vision. These cells are concentrated in the central part of the retina, known as the fovea, and are less sensitive to light compared to rods. Cones contain different pigments that allow them to detect different wavelengths of light, enabling us to perceive colors. In contrast, rods are responsible for vision in low light conditions but do not perceive color. Therefore, cones are the correct answer for the cell in the retina responsible for color vision.

Viewers suffering Deuteranopes often confuse the following colors save
- A.
  
  Deep green with indigo
- B.
  
  Light blue with lilac
- C.
  
  Pale pinks with light grey
- D.
  
  Mid-reds with mid-greens
Correct Answer
A. Deep green with indigo

Explanation
Deuteranopes, individuals with a form of color blindness, often have difficulty distinguishing between deep green and indigo. This means that they may perceive these two colors as very similar or even identical.

All of the following are classification of colors except?
- A.
  
  Primary Color
- B.
  
  Secondary Color
- C.
  
  Intermediate Color
- D.
  
  Optical Color
Correct Answer
D. Optical Color

Explanation
The classification of colors includes primary colors, secondary colors, and intermediate colors. However, optical color is not a classification of colors. This term refers to the perception of color as a result of the interaction between light and the human eye. It is not a distinct category of colors like primary, secondary, or intermediate colors.

Rate this question:

Among sufferers of Tritanopes, what are the common colors often confused?
- A.
  
  Orange
- B.
  
  Dark purple
- C.
  
  Mid-Green
- D.
  
  Light blue
Correct Answer
A. Orange

Explanation
Tritanopes are individuals who have a specific type of color blindness, known as tritanopia. This condition affects the perception of blue and yellow colors. In tritanopia, the blue-yellow color channel is impaired, causing confusion between certain colors. The common colors that tritanopes often confuse are orange and light blue. Therefore, the correct answer is orange.

What is the science of colors called?
- A.
  
  Coloring
- B.
  
  Color art
- C.
  
  Calorimetry
- D.
  
  Colorogy
Correct Answer
C. Calorimetry

Explanation
Calorimetry is the scientific study of measuring heat and energy transfer in chemical reactions. It is not directly related to the study of colors. Therefore, the answer "Calorimetry" is incorrect and does not align with the question asking for the science of colors.
