Operator Scope of Action:
Operator First Added:
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:
$MyColor.red = 255
$MyColor.red = "#ff"
$MyOtherColor.blue = $MyColor.red (value of $MyOtherColor blue channel is that of $MyColor red channel)
$MyNumber = $MyColor.red (gives 255)
$MyString = $MyColor.red (gives "255")
