Question

Given below are two statements, one is labelled as Assertion (A) and other one labelled as Reason (R).
Assertion (A) : Cool shades make smaller rooms seem visually larger, and sunny and warm shades make the rooms cooler, calmer and more pleasant.
Reason (R) : Cool shades along with warm shades are used in every room of offices.
In light of the above statements, choose the most appropriate answer from the options given below.

• A. Both (A) and (R) are correct and (R) is the correct explanation of (A).
• B. Both (A) and (R) are correct but (R) is NOT the correct explanation of (A).
• C. (A) is correct but (R) is not correct.
• D. (A) is not correct but (R) is correct.

Hint:

Be on the lookout for compound statements in assertions.
"Warm shades make rooms cooler" is a clear physical contradiction, making the assertion immediately false.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
Color psychology in interior design focuses on how different wavelengths of light affect human perception of space, temperature, and mood.
Colors are generally classified into cool colors (receding) and warm colors (advancing).

Step 2: Detailed Explanation:
Let us analyze the statements carefully:
Assertion (A): "Cool shades make smaller rooms seem visually larger, and sunny and warm shades make the rooms cooler, calmer and more pleasant."
The first part of the statement is correct: cool colors (blues, greens, purples) have longer wavelengths and appear to recede, making small spaces feel larger.
However, the second part of the statement is incorrect: sunny and warm colors (reds, yellows, oranges) stimulate the nervous system, make spaces feel cozier and visually smaller, and make rooms feel warmer and more energetic, not cooler and calmer.
Therefore, Assertion (A) is incorrect due to this physiological inaccuracy.
Reason (R): "Cool shades along with warm shades are used in every room of offices."
Modern office design employs a balance of both cool and warm shades across various spaces (such as using cool, calming blues in work bays to promote focus, and warm, energetic yellows or oranges in cafeteria or break rooms to encourage socialization).
This balanced combination is commonly applied across office environments to optimize productivity.
Therefore, Assertion (A) is incorrect, but Reason (R) can be considered correct under general interior design and color schemes.

Step 3: Final Answer:
(A) is not correct but (R) is correct.
