LOR in blue ink or black ink? - impx6

[ArchivalUser]

I read the INFORMATION FOR IMG in ERAS. It says there:
"Original Letters of Recommendation signed by the letter writer in blue ink"

My LORs are all signed in black ink. Will they accept this or should I have it signed in blue ink?

Need input, thanks

In your case it is better to send copies of the letters to ERAS and carry originals with you at the time of interview.

IT DOES NOT MATTER WHETHER ITS BLUE OR BLACK INK. AS LONG AS ITS ORIGINAL THEY WILL PUT IT AS ORIGINAL. CALL ERAS IF YOU ARE STILL NOT CONVINCED.

Follow instructions to be safe and avoid delays. I also read it needs to be signed in blue.
