What to write in a paint column? HHHmmmmm.... It seems that whatever can be written already has been.
I wonder what the first application of color was. Could it have been charred wood on a rock? Whatever it was, there probably was not too much concern over the consistency of color value, or the depth, flow and travel of the paint. Exotic pigments, additives, solvents, durability and gloss were not issues as they are today.
