Which statement about bow-ties is true regarding brightness impact?

• A. Bow-tie size and darkness have no relation to brightness.
• B. The bow-tie's darkness and size can affect the appearance of brightness.
• C. Bow-ties only affect color, not brightness.
• D. Bow-ties only affect symmetry, not brightness.

Answer: (B)

Bow-ties are light-performance patterns that can disrupt how light is returned to the observer. Their impact on brightness depends on how pronounced they are: a larger, darker bow-tie blocks or diverts more light, which makes the diamond look less bright. A small or faint bow-tie has a much smaller effect on the overall brightness.

This is why the statement that the bow-tie’s darkness and size can affect the appearance of brightness is the best choice. It directly ties light return to the visible bow-tie pattern, whereas claims that bow-ties don’t influence brightness or only affect color or symmetry miss the real impact on light performance.
