What pen do people use to sign on light paper (sulfuric acid paper)?

I hadn’t really noticed this before when signing images, but today, at the equipment signing session, I found that it’s very difficult to write clearly with a regular gel pen on bright images. I wonder what kind of pens everyone uses for signing.
Direct electronic signature, print together
Electronic signatures are good, but sometimes once you sign it, you can’t change the image anymore, which is quite troublesome.
