What is the font color of the wedding invitation? The invitation is red. Urgent!

At present, invitations are usually printed with a printer in advance, and you only need to fill in the names of relatives and friends. The font color is generally black, which is the carbon ink we use in school. Other colors are not solemn. In addition, try to use a calligraphy pen with a curved tip when writing. The written words are thick and beautiful, but they are not beautiful when written with ballpoint pens or other fine tips.
