1.
What is the science of color called?
Correct Answer
A. Chromatics
Explanation
Chromatics is the science of color, specifically the study of the perception and properties of colors. It involves understanding how colors are produced, how they interact with light and other colors, and how they are perceived by the human eye. This field of study encompasses various disciplines such as physics, biology, psychology, and art. Chromatics helps us understand the different aspects of color, including its wavelength, intensity, and hue, and how these factors affect our perception and interpretation of color.
2.
How many types of colors can butterflies respond to?
Correct Answer
A. Six colors
Explanation
Butterflies can respond to six different colors. This suggests that they have the ability to perceive and distinguish between a variety of colors in their environment. This may be important for various aspects of their behavior, such as finding food sources or mates, as well as for camouflage and predator avoidance.
3.
What is the most complex color vision system?
Correct Answer
B. Stromatopods
Explanation
Stromatopods have the most complex color vision system. Stromatopods are marine crustaceans commonly known as mantis shrimps. They have an impressive array of photoreceptor cells in their eyes, allowing them to perceive a wide range of colors, including ultraviolet light. Their eyes are divided into three regions, each specialized for different tasks, such as detecting color, polarization, and motion. This complexity in their visual system enables stromatopods to have exceptional color discrimination and visual communication abilities.
4.
When was the rainbow color spectrum made public?
Correct Answer
D. 1671
Explanation
In 1671, the rainbow color spectrum was made public. This suggests that prior to this year, the knowledge and understanding of the rainbow's color spectrum were not widely known or accessible to the public. It is likely that a significant scientific discovery or publication occurred in 1671, which brought attention to the phenomenon of the rainbow and its specific colors.
5.
Who is the first to describe the rainbow color spectrum?
Correct Answer
D. Isaac Newton
Explanation
Isaac Newton is credited with being the first to describe the rainbow color spectrum. In his work "Opticks" published in 1704, Newton conducted experiments with prisms and demonstrated that white light is composed of a spectrum of colors. He observed that when white light passes through a prism, it separates into its constituent colors, creating a rainbow-like spectrum. Newton's groundbreaking work laid the foundation for our understanding of the nature of light and color.
6.
When was the trichromatic theory proposed?
Correct Answer
D. 1801
Explanation
The trichromatic theory was proposed in 1801.
7.
What are colors obtained naturally without mixing called?
Correct Answer
B. Primary colors
Explanation
Primary colors are colors that cannot be created by mixing other colors together. They are considered the building blocks of all other colors. In the subtractive color model, the primary colors are red, blue, and yellow. These colors can be combined to create a wide range of other colors. Therefore, the correct answer is Primary colors.
8.
Which of these would you use for coloring?
Correct Answer
C. Brush
Explanation
A brush is typically used for coloring as it allows for more control and precision compared to a pencil or pen. Brushes are commonly used in various art forms such as painting, watercolor, and calligraphy, where different brush strokes and techniques can create different effects and textures. Ink can also be used for coloring, especially in ink wash paintings or illustrations, where the brush is dipped in ink and then applied to the surface.
9.
What kind of cells makes perception of colours possible in humans?
Correct Answer
D. Cone cells
Explanation
Cone cells are responsible for making the perception of colors possible in humans. These cells are located in the retina of the eye and are sensitive to different wavelengths of light, allowing us to see and distinguish various colors.
10.
What type of colours are obtained from other colors?
Correct Answer
A. Secondary colors
Explanation
Secondary colors are obtained from other colors through the process of mixing primary colors. When two primary colors are combined in equal amounts, they create a secondary color. For example, mixing red and blue creates purple, mixing blue and yellow creates green, and mixing red and yellow creates orange. Therefore, secondary colors are derived from the combination of primary colors.
