Platinum is a color that is the metallic tint of pale grayish-white resembling the metal platinum. The first recorded use of ''platinum'' as a color name in English was in 1918.〔Maerz and Paul ''A Dictionary of Color'' New York:1930 McGraw-Hill Page 202; Color Sample of Platinum: Page 113 Plate 45 Color Sample A3〕 ==Platinum in human culture== Awards * A ''platinum'' award is not as prestigious as a ''diamond'' award, but it is more prestigious than a ''gold'', ''silver'', or ''bronze'' award. Credit Cards * A platinum credit card has a higher credit limit and a lower interest rate than a regular credit card; it is only available to someone with a good credit rating. Literature * In Isaac Asimov's Galactic Empire as depicted in his Foundation series, the monetary unit of the Galactic Empire, the ''galactic credit'', is solidly backed because it is convertible to pure platinum—the Galactic Empire is on the platinum standard. Marriage * A married couple's 70th wedding anniversary is called their ''Platinum Anniversary''. The 70th anniversary of any important event can be referred to as a ''Platinum Jubilee'', although this term is seldom used. Music * a platinum album is an album whose sales figures have reached a certain amount. This threshold differs from market to market - in the United States, a platinum album is one that has sold at least 1,000,000 copies. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Platinum (color)」の詳細全文を読む スポンサード リンク
