Common Pitfalls
Translation Traps (for Russian speakers)

- Не путать с более распространённым "royal blue" (королевский синий), который является другим, обычно более ярким оттенком.
Common Mistakes
- Incorrect apostrophe placement (e.g., "kings' blue" for multiple kings).
- Using it as a general adjective for any blue (e.g., "the king's blue sky").
- Confusing it with the more common 'royal blue'.
