Question

Colour origin from

• A. Light
• B. Sound
• C. Line
• D. Tone

Hint:

Colours are a result of how different wavelengths of visible light are absorbed or reflected. Without light, there is no colour.

Answer 1

The Correct Option is A

Step 1: Understanding what 'Colour' means
Colour is the visual perceptual property corresponding to categories like red, blue, yellow, etc.
It is perceived by humans based on the way objects reflect or emit light.

Step 2: Scientific origin of colour
Colour originates from the phenomenon of light.
When white light passes through a prism or reflects off an object, different wavelengths bend or reflect differently.
This results in the appearance of different colours to the human eye.

Step 3: Elimination of incorrect options
(B) Sound $\Rightarrow$ Sound is not related to colour; it is related to vibrations and hearing.
(C) Line $\Rightarrow$ A line is a geometric figure, not a source of colour.
(D) Tone $\Rightarrow$ Tone is used in sound and music, not in colour generation.
Conclusion:
Thus, colour originates from the interaction of light with objects.
\[ \boxed{\text{Correct Answer: (A) Light}} \]
