One of my favorite ways to add subtle accents and cues is with grey gel pens. Surprisingly, they can vary a lot because of the tone of the color. Here are a few of my favorites!

Like my Black Gel Pen review post, I’ll be using the following criteria to rank these pens:

• Smoothness (1 being scratchy, 5 being uber smooth);
• Opacity (1 being thin ink, 5 being nice and dark);
• Style (1 being basic utility/nothing special aesthetically, to 5, aesthetically thoughtful and awesome); and
• Writability (a nonsensical term I’ve made up, for how pleasant it is to write using the pen for a long time, on a scale 1, not particularly pleasant, to 5, very pleasant overall).

Pilot FriXion Erasable Gel Pen, 0.7
Smoothness: 4/5 | Opacity: 3.5/5 | Style: 3.5/5 | Writability: 4/5
I was really excited to try this unique pen. It’s a bit too bold for me but I do like having it available. It has a lovely inky quality to it, almost like a fountain pen effect, and it’s very smooth.

Pilot Juice Gel Pen, 0.38
Smoothness: 4/5 | Opacity: 4/5 | Style: 3.5/5 | Writability: 4/5

Uni-ball Signo UM-151 Gel Pen, 0.38

This is the winner grey gel pen for me! The color is a cool grey – not too warm, nice and pale but still legible, and overall a great, smooth pen. If you’re in the market for a cool grey pen, this is the one for sure. The other two in this post are much more on the warm side.
