My thanks to Glenn for the ink sample!
Kyo Iro is a Japanese ink series inspired by the sights of Kyoto. It’s sold by TAG Stationary. Moonlight of Higashiyama is part of a 5 colour ink series. It’s a dark orange / burnt orange ink that shades easily even in a Japanese fine nib. It goes from a strong red - brownish orange to a light brown. Personally it’s not my kind of brown or orange but it is definitely an interesting colour for the ink collection.
