Hi, I am tracking down a word that I once discovered and have since lost... it is used to describe the use of white outlines in art. Hopefully I can find it again here among the intelligentsia. Appreciated.

Welcome and stick around. Someone will probably know.

Thank you and fingers crossed... I know it's an obscure art term, but I'm hopeful.

I know we have one artist who comes here periodically,
maybe she will have the term.

I asked my daughter (an artist), and she had no idea, but there are lots of artists in these part, so I'll ask around.

I know BranShea is an artist, not seen here for a while,
but if she sees this she may know.

Thanks so much for continuing the investigation.

Here's a response from an artist that may be of help to you:

The use of white outlines in art : I wish your friend could give a little more info, as to period and type of art, as white outlines mean that the artist had to use a white drawing tool on a dark background, and those instances are almost non-existent. But there a 2 instances in which lines of white can be discerned:
" pentimento", a painting beneath a painting, resulting in white ares left unpainted in the primary level painting coming through the overlying painting
"synopie", an undersketch for a fresco in which the predominant red-ochre color of the drawing is highlighted in white.

Neither of the above represents what I would call a true outline, however. If this mystery word comes to light, let me know, as I have degrees in art history as well as studio art, and frankly have never heard of a word for white outlines.

Edit: And then she added:

The word "chiaroscura" is a general art term meaning from light to dark, and drawings about which that term can be employed often employ white lines and/or highlights .
