Black vs. Blue Ink: What Colour Ink Is More Professional?

What colour ink is more professional? Black ink, blue ink, old ink, new ink, home ink, work ink, what do YOU think? It’s confusing! The debate over black vs. blue ink goes something like this:

  • Legal documents: Blue
  • Passport paperwork: Black
  • Credit card applications: Blue
  • Writing cheques: Black
  • Taking notes in class: Blue

But why? Where’s the rhyme? Where’s the reason? When addressing the black vs. blue ink conundrum, seems like our best bet is to recommend a multi-ink pen and call it a day (FYI, here’s a good one: Metal Soft Touch Lyn Multi-Ink Stylus Pen). But we love a good riddle and we’re going to dig a little deeper than that. Below we unpack which colour ink to choose for signing, filling in and generally taking care of business on a daily basis.

When Is Blue Ink Best?

When you want to be able to see your signature easily against a sea of black print, and confirm the signature’s not a copy, blue is best. 

  • Credit Card Applications: Trying to get a credit card? Reach for the blue ink pen! Banks prefer blue because it’s easier to verify that the signature is legitimate and the documents are original when they’re signed in blue ink. Unlike black ink, a blue ink signature isn’t as easy to reproduce. If a document is signed in blue, it offers fraud detectors an easier ‘tell’ if the signature isn’t the original, inked version.
  • Other Financial Documents: Similar to credit card paperwork, a blue ink signature on other financial documents is harder to reproduce and easily differentiates an original document from a copy.
  • Legal Documents: What colour ink should be used to sign legal documents? When you’ve got to initial here, tick there and sign on the dotted line, page after page, the person checking the document wants to spot your signature easily and differentiate quickly between the original document you signed, and the million copies they need to make for distribution to the various interested parties. For these reasons, blue ink is best (and sincerely appreciated) by legal professionals far and wide.
  • Notarising: Although there is no law about which ink colour should be used to notarise documents (in fact, a law in the US requiring that notary public signatures be in black was repealed in 20131) most notaries prefer blue ink. It’s easier to tell an original from a copy.
  • Students and Memorisers Alike: Blue is a cool, calming colour and contrasts well, though not jarringly, against black. This means if you’re reviewing printed text, which is usually black, and you make notes in blue, your notes stand out more on the page — and in your head on the day of your exam.

When Is Black Ink Best?

For documents that will be scanned or photocopied or where your signature is very important (like on a passport application), it’s best to use black ink. Though dark blue ink may be acceptable, who wants to take the chance and run the risk of a paperwork rejection just because you didn’t have a black ink pen handy? Tip: If you’re the one handing out the forms or helping with the paperwork, set your customer up for success by giving them a customised black ink pen to complete their paperwork and keep afterwards for long-term branding.

  • Photocopying: Black ink tends to copy and scan better than any other ink colour. Go with black and save everyone the hassle of hard-to-read documents.
  • Writing Cheques: The best pen for signing a cheque is one with black ink. The contrast between black ink and a white or light-coloured cheque is ideal for authentication, and black ink scans better.
  • Passport Applications: Passport forms should be filled in using black ink.2 Passport forms get copied and digitised, and black ink tends to scan better than blue, which can show up very light depending upon the shade of blue ink used.
  • Tax Forms: If you’re only signing something, blue or black ink is fine. On the other hand, if you’re filling out tax forms by hand, generally black ink is the better choice so that the paperwork can be more easily scanned.3

What Colours Should I Avoid in Business Documents?

Though whether blue or black ink is more professional depends upon the business circumstances, there are a few other colours you can safely avoid. For form filling and signing, steer clear of red, purple and green, along with any light or metallic shades.

  • Red is hard to see when scanned or copied. It’s also used to make corrections and to flag suspicious or fraudulent activity, so unless you’re checking someone’s work or catching numbers that don’t add up, stay away from red.
  • Purple and green do not scan or copy well, increasing the chances you’ll need to resubmit documents.
