This property sets or returns the value of the blue channel of an RGB colour. The value may be set with a number (0–255) or hex number (#00–#ff). The return value (if coerced to a string or number) is always a number, i.e. 255 and not #ff. By comparison the rgb() operator requires that the values for all three colour channels be set. Examples:

$ = 255; 

$ = "#ff"; 

$ = $;  (value of $MyOtherColor blue channel is that of $MyColor red channel)

$MyNumber = $;  (gives 255)

$MyString = $;  (gives "255")
