Step 1: Understanding the Concept:
A complementary color scheme is based on two colors that are directly opposite each other on the color wheel. When placed next to each other, these colors create the strongest possible contrast and appear more vibrant.
Step 2: Detailed Explanation:
Let's analyze the pairs based on a standard RYB (Red, Yellow, Blue) color wheel:
(A) Blue \& Orange: Blue and Orange are directly opposite each other on the color wheel. This is a complementary pair.
(B) Red \& Green: Red and Green are directly opposite each other on the color wheel. This is a complementary pair.
(C) Green \& Yellow: Green and Yellow are adjacent to each other on the color wheel. This color scheme is called analogous, not complementary.
(D) Purple \& Yellow: Purple (or Violet) and Yellow are directly opposite each other on the color wheel. This is a complementary pair.
Step 3: Final Answer:
The pairs that represent complementary color schemes are (A) Blue \& Orange, (B) Red \& Green, and (D) Purple \& Yellow. Therefore, the correct option includes (A), (B), and (D) only.
