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 color channels be set. Examples:

$ = 255 

$ = "#ff" 

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

$MyNumber = $  (gives 255)

$MyString = $  (gives "255")
