Turquoise is sometimes described as a mixture of pale blue and green.
Geography
In slang form, the phrase "The Turquoise" refers to the waters of the Caribbean, which are shallow and therefore take on the color in sunlight.
Medicine
In holistic medicine, the color turquoise purportedly has a calming effect on patients, and is particularly used to treat patients prone to panic attacks or mania. To a lesser degree, mainstream psychiatric hospitals also use turquoise and other light shades of blue and green to calm patients by painting the walls in these colors. Turquoise is perceived by most people as the coldest of all colorscitation needed.
