Direct overblending of yellow and violet created a muddy area in a sunset. What would be a better colour sequence?

Correct answer: Yellow then an orange or red intermediate colour then violet

The governing concept is controlled colour blending, especially when colours are close to complementary opposites. Yellow and violet can become dull or muddy when scrubbed directly together in equal strength. Placing a warm intermediate such as orange or red between them creates a gradual transition and preserves the sunset glow. Option C is therefore correct. Black would dirty the passage, while mixing all colours destroys colour clarity.
