Gold or yellow wrapping is the safest, most celebratory default. Save black, white, blue, and green for their actual context (mourning dress and funeral-related items) rather than everyday gifts.
Hand the gift over with your right hand, or both hands for something more formal, and don’t be surprised if it’s set aside to open later rather than opened immediately in front of you.
A couple of smaller customs round this out:
- Gifts in threes are considered a lucky grouping, if you’re bringing several small items, three is a good number to land on.
- When a gift is opened in front of you, let the recipient unwrap it carefully rather than tearing the paper, ripping wrapping is seen as a little rude regardless of who’s doing it.
