GR translation: coaltar-impossible orange-brown

[John Bailey]

Coal tar is very thick and gluey (viscous) so it would be impossible
for this orange-brown light to make it through clearly.

Also this (wikipedia): As the 1900s began, the bulk of chemically
synthesized colors were derived from aniline, a petroleum product that
is toxic.[4] Originally, these were dubbed `coal-tar' colors because
the starting materials were obtained from bituminous coal.[16] Though
colors from plant, animal and mineral sources, which had been used in
earlier times, remained in use early in this century, manufacturers
had strong economic incentives to phase them out. Chemically
synthesized colors are easier and less costly to produce, and are
superior in coloring properties. Synthetic colors are also highly
concentrated, there are no limits on dosage level, and they are widely
available.[8] Their use has spread to include the food, paint,
coating, textile and plastics industries.
