Un valor de color RGB<\/strong> representa las fuentes de luz ROJA, VERDE y AZUL. (RED, GREEN, BLUE). En CSS<\/strong>, un color se puede especificar como un valor RGB<\/strong>, utilizando esta f\u00f3rmula:<\/p>\n\n\n\n\n\n\n\n

rgb(red,<\/em> green<\/em>, blue<\/em>)<\/pre>\n\n\n\n
Cada par\u00e1metro (rojo, verde y azul) define la intensidad del color entre 0 y 255. Por ejemplo, rgb(255, 0, 0)<\/em><\/strong> se muestra como rojo, porque el rojo se establece en su valor m\u00e1s alto (255) y los dem\u00e1s se establecen en 0. Para mostrar negro, configure todos los par\u00e1metros de color en 0, as\u00ed: rgb (0, 0, 0)<\/em><\/strong>. Para mostrar el blanco, configure todos los par\u00e1metros de color en 255, as\u00ed: rgb (255, 255, 255).<\/p>\n\n\n\n
Tonos de gris<\/h2>\n\n\n\n
Los tonos de gris a menudo se definen utilizando valores iguales para las 3 fuentes de luz:<\/p>\n\n\n\n

Valores RGBA<\/h2>\n\n\n\n
Los valores de color RGBA<\/strong> son una extensi\u00f3n de los valores de color RGB<\/strong> con un canal alfa<\/strong>, que especifica la opacidad de un color. <\/strong>Un valor de color RGBA<\/strong> se especifica con:<\/p>\n\n\n\n
rgba(red,<\/em> green<\/em>, blue, alpha<\/em>)<\/pre>\n\n\n\n
El par\u00e1metro alfa<\/strong> es un n\u00famero entre 0.0 (totalmente transparente) y 1.0 (nada transparente).<\/p>\n\n\n\n
