Step 1: Understanding the Concept:
In the Prang 12-hue color wheel, direct complementary color harmonies consist of pairs of hues situated exactly opposite to each other ($180^\circ$).
Step 2: Detailed Explanation:
Analyzing opposite pairs on the standard Prang 12-Color Circle:
1. Yellow and Purple (E): Direct primary-secondary complementary pair.
2. Yellow-Green and Red-Purple (A): Direct tertiary-tertiary complementary pair.
3. Blue-Green and Red-Orange (D): Direct tertiary-tertiary complementary pair.
(Violet and green are split-adjacent; Blue-green and red-purple are split-complementary).
Thus, pairs A, D, and E are true direct complementary harmonies.
Step 3: Final Answer:
Therefore, the correct answer is A, D and E only, corresponding to option (B).
