Ostrich ink is a very very old name in ink manufacturing in China and last year they bring out their first ever set of color ink in the form of the " Flower Series " at 15ml ea. for a collection of 12 colors; I recently get hold of a set of this in the plain form ( there is also the same set but with gold glitter ). A lot of back and forth communique with the factory tech finally get me informed that while the ink is not marketed or intentionally designed for mixing it is none the less mixable. So I set out to do a sampling of the ink and the combo The combo will have to wait a bit later but I've shoot a sample of the ink as they are The text is written with a 3B pencil and the gray card is a Kodak 18% gray for those who know how to color balance it; the paper is Rhodia dot pad. I forget to put the name of one of the color, that one is termed y the Mfr " Withered Sakura "
