The blending ratio can also be expressed as a percentage. such as RGB (100%,0,0) is also red, when the value is 0 o'clock, the percent sign can omit do not write [16]: "#" begins with "#rrggbb" The form of the 16-digit color, each of the value range is "0~f", the numeric size of the table color concentration, such as #ffffff to indicate the maximum proportion of each color, in addition, if #rrggbb each bit of the same value, can be abbreviated to #rgb.
