The best pencils for marking on dark wood

4 April 2025 Stan

I’ve found myself with a big old board of katolox wood on my bench. Sometimes referred to as Mexican ebony, it’s a very dark wood with almost a deep purple hue. As I started to plan how to get my parts out of the board, I was suddenly reminded how difficult it is to see your markings on dark woods like walnut, rosewood, ebony, and now katolox.

For years, I’ve used a white pencil on dark wood, but a while ago Bob Van Dyke gave me a silver pencil and declared that it’s the best tool for marking up dark wood. While Bob likely wins the award for “the person you should most likely take their word for,” I thought it would be interesting to try a few different pens and pencils I’ve heard people using and test it out for myself. Annoyingly, this test had legs and when I mentioned it to Bob, he informed me that he no longer uses the silver pencil he gave me and I was forced to add in his new favorite—a blue pencil. I mentioned it to my colleague Amanda Russell and she was confused that anyone uses anything other than a yellow pencil.

So, off I headed to the nearest Michaels to grab a reasonable variety of options of each of the favorites—including a Prismacolor sharpener that sharpens pencils with a shorter tip (higher angle) to sharpen each pencil with the same angle. I have found that the softer ‘leads’ of colored pencils last longer with a shorter tip.

Here I’ll share my thoughts on a few different writing implements and a Mike Pekovich–inspired ~~cheat~~ bonus tool.

This is not a scientific examination. I did my best to keep the playing field level. The photos might not tell a truly accurate story and I’m sure my opinions won’t be truly unbiased; but between the two of them, you might be able to make sense of everything. Last note: these are not all of the pencils and pens I tried, just the ones worth sharing.

*I apologize for the crop of some of the photos… I did a dumb

Prismacolor Verithin Pencil

I included this pencil because it seems like the obvious choice. White on dark… can’t lose right? Wrong. Years ago this might have been the first pencil I bought in my quest. I thought that a high-dollar white pencil would surely do the trick. Nope. I’m sure it’s great for its intended purpose of drawing on paper, but I found it far too smudgy on wood and compared to the others options white pencils didn’t stand up much at all.

Prismacolor Silver Pencil – Get one!

Even though at first glance a silver pencil is darker than a white pencil, in use the reflectivity of whatever they’re putting in the pencil makes up for it in spades. I’m sure the difference would be negligible in an unlit workshop, but turn on some lights and the silver pencil easily becomes the most visible of the options shown here.

For me, the Prismacolor silver was a stand out in the patch. The hardness of the lead was better than the other silver pencils I tried, allowing for a finer line. The reflectivity was also the best. If I had to pick one pencil to have in my toolbox for use on dark woods, this would be it.

Prismacolor Blue Pencil – Great up close

This is not the exact pencil Bob told me about (Prismacolor Col-Erase Blue #20044), so I’ll keep searching and if I find one I’ll add an update

While barely visible from a distance, this Prismacolor Premier Ultramarine pencil POPPED when you looked at it up close. It certainly doesn’t show in the photos, so you’ll need to trust me on this; but the blue pencil is the most ‘intense’ and easiest to see when focusing. If I were following a long line while cutting a part out on the bandsaw I could see this pencil line being the easiest to identify and follow. This pencil is definitely worth a try!

Faber-Castell Light Cadmium Yellow #105 – Great all around

There are few woodworkers I know that I absolutely trust and who work with walnut as much as Amanda Russell. So when she mentioned yellow pencil I knew I had to try one. She’s absolutely right. The yellow pencil seems like an all-around great marking implement for dark woods and of the two I tried the Faber-Castell barely edged out the Prismacolor.

Sakura White Gelly Roll Pen – Another must-have!

If colored pencils are too sharp, they will break the moment you touch them to wood. Therefore if you need a truly fine line, get a Gelly pen. These Japanese pens are quite popular online. I’m not sure where I heard about this as an option for marking on wood, but they work very effectively. I bought a three-pack with a variety of line widths and have used them often. My go-to has been the 0.5 mm pen. It makes a nice crisp line that is perfect for marking out precise joinery. Up close, it isn’t the easiest to see of the options I share here, but it’s the best for fine lines. From a distance though, the Gelly Roll pen is far and away the best performer. In fact, this whole thing started as I was trying to mark wood and look at it from a distance in order to dial in how the grain interacted with the par—from a few feet away, the Gelly Roll is EASILY the winner. I think every woodworker should pick up a pack of these pens and try them out.

Blue Tape Bonus Hack?

I can’t possibly end this post without mentioning Mike Pekovich’s opinion that the best line on dark wood isn’t made by a pen or pencil. It’s made by a sharply sliced blue tape line. It’s hard to argue with that!
