History for Callifolio Heure Dorée

A honey-golden yellow ink, Callifolio Heure Dorée comes in a 35 ml bottle or a 50 ml bag. It is possible to store it in the bag, but the opening will be too small for some nibs, let alone pens. It is also hazardous to press on the bag to get the ink up to the brim, making it possible to fill a pen.
"Heure Dorée" means "golden hour" as in that hour around sunset and sunrise where the light is so coveted by photographers. The ink seems to lean warmer or colder depending on what you compare it to; it has a bit of brown in chromatography. It is the lightest ink in the Callifolio series, but not too light for reading (depending on one's tastes).
Heure Dorée shades well in any nib size, but the larger the nib and wetter the pen, the more this will be evident.
