…the many pinks, browns, and a blue-green called “teal” plus the indigo blue.
Synthetic dyes would not be invented until the 1850’s when a man accidentally invented “mauveine” while trying to find a cure for malaria. With a huge fashion industry in the 1870’s and a big interest in science at that time, most of the really bright and intense colors you see today were invented around that time, 100 years after the Revolutionary War.
It was rare to have bright or intense colors in 1776 unless you were royalty.
