Match the following. 
Step 1: Understanding the Concept:
This question requires knowledge of fundamental concepts in color theory to match the visual examples with the correct terms.
Step 2: Defining the Terms:
P. Complementary: Colors that are opposite each other on the color wheel (e.g., red and green). They create high contrast.
Q. Spectrum: A continuous band of colors, like a rainbow, showing the full range of visible light.
R. Cool: Colors associated with coolness, like blues, greens, and violets.
S. Harmony: The pleasing arrangement of colors in a design, based on established color schemes (e.g., analogous, triadic).
Step 3: Analyzing and Matching the Images:
Image 1: Shows a continuous gradient of all colors, transitioning smoothly from one to the next. This is a visual representation of the color Spectrum (Q).
Image 2: Displays several palettes composed exclusively of blues, greens, and purples. These are classic Cool (R) colors.
Image 3: Shows different sets of colors that are aesthetically pleasing and work well together. This illustrates the concept of color Harmony (S).
Image 4: Shows pairs of colors that are opposites, creating strong contrast (e.g., yellow and purple, red and cyan, blue and orange). These are Complementary (P) colors.
Step 4: Final Answer:
Based on the analysis, the correct matching is:
1 $\rightarrow$ Q
2 $\rightarrow$ R
3 $\rightarrow$ S
4 $\rightarrow$ P
This corresponds to the sequence 1Q, 2R, 3S, 4P, which is option (B).
