The wiki also says use a brush

Since I wrote it I wrote from my own perspective, wherein I always use a brush, the guide may not be totally suitable for using a pin - I've never done so but others use nothing else, so it can be done.
Personally I often find a 000 or 0 size brush with a good tip better than a very fine (5/0 or 10/0) size as it has more give and I get better control. And while I'm plugging my 1337 skillz I'll point out as an example
Icebreaker, who was painted entirely with 1 and 0 brushes. The brushes often don't last in this condition very long so I do also use the smaller brushes, but I prefer to use a 000 or 0 for detailing.
As for flesh tones, I use a mix of Citadel Elf Flesh (and sometimes Dwarf Flesh) and white. They're all I've ever used so I swear by them.
