A showdown was held to determine the world’s blackest permanent marker—a competition focused solely on the intensity of black ink.
Permanent markers are a staple in everyday life. They dry quickly and can be used on various surfaces, making them indispensable stationery items. Among them, black permanent markers are especially common, with most people likely having at least one on hand.
There are many different black permanent markers available from various companies, making it hard to know which to choose. While researching markers, a ranking article by MONOQLO titled “Top 8 Recommended Permanent Markers of 2023 – Unfading Black Pens Thoroughly Tested!” was discovered. The MONOQLO article evaluated markers based on two criteria: resistance to fading once dry and usability on different surfaces. However, it did not assess the actual blackness of the ink.
That gap inspired the launch of a new test: a contest to find the world’s blackest permanent marker, evaluated specifically by blackness.
The following eight markers from both domestic and international brands were selected for the blackness comparison:

A total of eight permanent markers were evaluated in this blackness showdown.
Each marker was tested on business card–sized matte paper, with two layers applied in a cross pattern to ensure full coverage.

A measuring device was used to determine the average reflectance rate between 400nm and 700nm wavelengths. From that, the light absorption rate was calculated. A higher absorption rate indicates a blacker ink.
Here are the top three blackest markers:
1st Place: Tamiya “Paint Marker XF-1 Flat Black”
2nd Place: Holts “Color Pen”
3rd Place: Teranishi Chemical “Magic Ink ML-T1 Black”
Tamiya’s marker achieved a light absorption rate of 97.3%, far surpassing others, most of which were below 95%. Its matte finish proved to be a major factor, showing the true power of low reflectivity.
Holts’ Color Pen took second place, representing the strength of a century-old British company.
Teranishi’s Magic Ink came in third. As Japan’s original permanent marker, it remains an impressive option—especially for those wanting a super-black, easy-to-use pen.
In this contest to find the blackest permanent marker, Tamiya’s Paint Marker XF-1 Flat Black took a commanding lead. Writing on black construction paper with this marker still produced clear, visible letters—an impressive display of contrast.

Unfortunately, this standout product appears to be discontinued, with no stock listed on Tamiya’s website or Amazon. A shame, given its incredible blackness. A restock from Tamiya would surely be welcomed.
To close the blackness showdown, another contestant takes on the challenge. While Tamiya’s marker had an impressive 97.3% light absorption, our water-based acrylic paint called “Musou Black Paint” achieves a more extreme blackness. When airbrushed, it reaches up to 99.4% light absorption, and even with a normal brush, it achieves up to 98.9%, maintaining ultra-low reflectivity.

“Musou Black Paint” is available on our store in 100ml bottles, 1L bottles, and bulk sets of 20x 100ml bottles. We also offer a painting service.
For anyone seeking a new level of blackness, our paint will offer an entirely different dimension.
That is all for this blog, see you in the next one!
