Cecil, so sorry. For wedding invitations, is there a rule that the words in the card (or the paper in the card) can not be written in red?

Reply: Nobody writes in red. Black ink or nowadays silver or gold.

These are some considerations:

1. The traditional wedding cards are written in black ink. In modern times, some use gold or silver pens. These are perfectly okay.

2. While RED or pink wedding cards are fine or okay. It is odd to write someone's name in RED. 

3. Even if it is perfectly okay for the sender (wedding couples) who feel writing in RED is okay to them. But the consideration is for the person receiving the invitation.

4. Some may feel disturbed or feel uneasy to see their name(s) in RED or in "BLOOD" colour.

5. Thus, to be on the safe side, why be the odd one out? Please DON'T do it!
