Nowadays, it doesn't really matter. There used to be an issue with photocopiers not reproducing blue. However, often now - because documents are in black, the opposite will be true, and you can be asked to sign in blue or some other color to ensure the original (not photocopy).
Electronic signatures are legal - with a bunch of caveats depending on the what use, where it's going. You can do a certified electronic signature thru some service (I forget the details) but it gives a certification number/authentication which you then use with your electronic signature. I just don't remember all the details of this - but it's essentially like electronically notarizing your signature, and then with that info your e-signature is acceptable as a genuine, legal signature. For other things, you can often just sign them noting "electronic signature" - usually things not requiring the full legal impact.
Ah, the pocket protectors - lovely. I refused to ever wear one - but found them quite useful for my collection of writing utensils when in school - pre back-pack days. Even with a back-pack - I tend to have some very fine tip pens/pencils/lead-holders/markers. The ppp was a perfect size to house what I schlepped around, and made it easy to pull out. As a nerd, I will admit, many classes where my notes include a couple of different colors. And lots of very straight lines (carting around a 6" mini-ruler), taken on engineering pad (which is like graph paper, but gridded only on the back, so shadowed on the front. I'm still addicted to this stuff - which now is like $6-$7 a pad at an office supply - but I make DH bring it home.
