Proporciona código hexadecimal a la función (por ejemplo, #eeeeee), devuelve una matriz de valores RGB.
function hex2rgb( $colour ) ( if ( $colour(0) == '#' ) ( $colour = substr( $colour, 1 ); ) if ( strlen( $colour ) == 6 ) ( list( $r, $g, $b ) = array( $colour(0) . $colour(1), $colour(2) . $colour(3), $colour(4) . $colour(5) ); ) elseif ( strlen( $colour ) == 3 ) ( list( $r, $g, $b ) = array( $colour(0) . $colour(0), $colour(1) . $colour(1), $colour(2) . $colour(2) ); ) else ( return false; ) $r = hexdec( $r ); $g = hexdec( $g ); $b = hexdec( $b ); return array( 'red' => $r, 'green' => $g, 'blue' => $b ); )
