1890s

The 1890s were sometimes referred to as the "Mauve Decade," because William Henry Perkin's aniline dye allowed the widespread use of that colour in fashion, and also as the "Gay Nineties", under the then-current usage of the word "gay" which referred simply to merriment and frivolity, with no connotation of homosexuality as in current-day usage.
