Why the Button Is Bright Orange
The button’s background color is specified as #FC9630. This is a hexadecimal color code that uses the RGB (red-green-blue) method to specify a color. The six hexadecimal digits are divided into three pairs: FC specifies the amount of red, 96 specifies the amount of green, and 30 specifies the amount of blue. Each pair represents a value from 00 (zero intensity) to FF (maximum intensity, or 255 in decimal). The red component, FC, equals 252, which is almost the maximum possible value of 255. The green component, 96, equals 150, a moderate amount. Red and green in approximately equal amounts produce yellow, but because this color has considerably more red than green, the result shifts toward orange. The blue component, 30, equals 48, which is relatively small. It contributes a little blue light to the mixture and helps determine the precise shade of orange.
The button looks bright because it combines a nearly maximum red intensity with a substantial amount of green. The relatively low blue intensity keeps the color orange rather than making it pale or white.
