Which sequence is more natural for a sunset transition from yellow-orange to blue-violet?

Correct answer: Yellow-orange, then red-orange, red-violet, and blue-violet

The governing concept is a continuous colour transition using related intermediate hues. Red-orange maintains a warm connection with yellow-orange, while red-violet and blue-violet progressively move toward the cool end of the sequence. Blue-green, black-white interruptions, or a direct jump do not provide the same smooth hue progression. Thus option A creates the most coherent sunset gradation.
