Question

Choose the odd one out.

• A. Indigo
• B. Blue
• C. Pink
• D. Purple

Hint:

When classifying colors, group them by temperature (warm vs. cool) or by their presence in the natural rainbow spectrum (VIBGYOR).
Here, Indigo, Blue, and Purple are cool-toned colors, while Pink is a warm-toned pastel color.

Answer 1

The Correct Option is C

Step 1: Understanding the Concept:
To solve "odd one out" classification questions, we must find a common attribute shared by three of the options that is not shared by the fourth.
In this case, all four options are colors, so we must analyze their classification based on the light spectrum or color theory.

Step 2: Detailed Explanation:
Let us analyze the colors listed in the options:
- Indigo and Blue are standard spectral colors that belong to the visible light spectrum.
They are part of the seven colors that make up a rainbow, represented by the acronym VIBGYOR (Violet, Indigo, Blue, Green, Yellow, Orange, Red).
- Purple is closely associated with Violet in common classifications, and both are cool, short-wavelength colors.
In many logical classification contexts, Blue, Indigo, and Purple are grouped together as neighboring cool colors on the color wheel.
- Pink is a non-spectral, warm color.
It is produced by mixing red and white light or pigment, and it does not appear on the visible spectrum of a rainbow.
More importantly, Indigo, Blue, and Purple are cool-toned colors located adjacent to each other on the color spectrum, whereas Pink is a warm-toned pastel color.
Therefore, Pink is the most distinct color in the group and is the odd one out.

Step 3: Final Answer:
The odd color out among the choices is Pink.
