The 10 meter mark is 3 links painted black.
The 20 meter mark is two sets of 3 blank links separated by 2 links painted white.
The 30 meter mark is three sets of 3 black links separated by 2 links painted white.
The intermediate 5 meter marks are 2 black links.
I've seen guys using spray paint for the markings but I figured that hand painted enamel paint would be more durable. Also, I surrounded the black markings with white to enhance the visibility.

I'll swap it with the newly galvanized but unmarked 30 meter chain currently on Pachuca.
