I've been interested in fountain pens for a little over two years now, but never had anyone to mail a letter to until now. Since I use my pens for school almost exclusively, I don't have a lot of inks; the two I use the most are a blue Parker quink ink I found at Office Depot, and a black Sheaffer skrip ink (I do not like this one, as it is a very shady black with brown undertones... I like strong black inks). The rest of my inks are Diamine Marine, Diamine Oxblood, Diamine Eclipse, and Diamine Cocoa Shimmer.
To be honest, I like Cocoa Shimmer and Oxblood the best, specially Oxblood, but I worry that using a red ink might come off as rude.
Do you think I should skip Oxblood or is it okay for it being "brown-ish"? I'd really like to read your thoughts on this, as I am very much inexperienced on the topic.
