The order of operations seems odd on the exemplar. It looks to me as if the gold was painted over another color in some places. A change of plan? Flakey gilding? I have chosen to start with the gold, as is seen in other manuscripts. Also note the relatively transparent sepia ink for the text.
I made my own paint and ink from ground pigments and gum Arabic. The red and blue green were leftover from the Novgorod gospel pages, and are synthetic ultramarine mixed with a little terre verte, and synthetic vermillion.
The sepia ink is red ochre, yellow ocher and raw umber in a dilute gum Arabic binder. The gold is Daler & Rowney brand commercial ink.
The scroll is done on pergamenta. Text provided by the royal scribe, calligraphy is a variation on my Cyrillic pseudohand.
The white lining, done with a thin whippy brush, makes the header come alive.
