RYB - Red Yellow Blue, used by artists in mixing paint.
These gym-suits stayed dark green after weekly washings. A surprising accomplishment compared to the boys denim jeans that would fade to light blue after a year of washing machine and dryer abuse. Later, manufacturers decided this 'pre-washed aged denim' look was a fashion statement and began 'stone washing' jeans before they hit the stores. I know they used real stones, since I once found a 1" piece of pumice stone in the pocket of my new jeans.
The required non-stretch gym-suit was during the days of Twiggy when we wore stretch cotton t-shirts and our miniskirts eventually got so short school officials finally decided to allow girls to wear pants to school just before I graduated in 1971. Then came the thick stretchy polyester fabric that made its first debut as 'leisure suits' quickly adopted by senior citizens as 'comfortable,' thereby dooming it as a fashion choice for anyone under the age of 50 until the industry figured out how to knit a thinner textiles and dye it any color other than file cabinet beige. A process called 'filament dyed' where the synthetic material is dyed before or after being extruded into yarn, making the color part of the fiber.
Did you grow up in one country and then move to another? If you did, you may have experienced cultural color meanings that are different than you are used to.
Gold represents wealth in most cultures; however, too much of it could be interpreted as vulgar or in bad taste.
In the United States, red means danger - fire engines and stop signs. Black is for mourning and for serious business clothing. White is the color for wedding brides.
In Japan, white is the color for grief and mourning., although also associated with purity and truth. Grey is expressed as 'nezumi' meaning mouse, and can be described as purplish, greenish, light or dark. Blue symbolizes luck and university students wear blue suits for job interviews.

Pigments through the Ages
Dye Colors by Century
Minerals are used to create pigments for painting; textiles are colored using natural dyes derived from plants and animals that change the color of natural fibers like linen, cotton, wool and silk. Plant dyes are made from roots, berries, bark, leaves, wood, fungi, and lichens.
Some dyes were so difficult to create that they were reserved for royalty. Royal purple is from of a rare sea creature, whose secretions change from milky white underwater to a powerful dye when exposed to the air, was reserved for royalty by Queen Elizabeth due the the scarcity and cost. Dating back to ancient Phoneticians, Tyrian purple came from a species of sea snail Bolinus brandaris, the dye called Murex, rumored to be worth its weight in gold.
"... The Tale of Genji, who called herself Lady Muraki or Lady Purple. The Japanese had their own purple-giving shellfish - Rapana bezoar - but it was very rare..." 
Indian Collecting Cochineal
In 1856 William Henry Perkin was an 18 year old prodigy, at the Royal College of Chemistry in London, who was researching how to make synthetic alternative to quinine, a malaria remedy made from the bark of a tree, and discovered that a residue in a beaker created a beautiful color. Dubbed 'Tyrian Purple' after the famous expensive sea shell dye, this color was actually closer to mauve, a pink-lavender color, historically marking the advent of aniline synthetic dye.
Synthetic dyes are made from petroleum and are sometimes combined with minerals. Many new colors have become available and now, bright purple is inexpensive, magenta and yellow can be so bright that they are compared to 'highlighter' pens. Synthetic fabrics are dyed before being extruded then knitted or woven. Sometimes the color is printed on later. This is where paint and dye overlap both historically and now.
To learn more about the history pigments and dyes, I recommend the thorough book, Color, A natural History of the Palette, by Victoria Finlay.
