You'll have to go a bit down the abstraction layer to find out the reason why. x86's comparison/jump instructions are binary (since they can be easily computed in a few clock cycles), and that's the way things have been.

If you want, many languages offer an abstraction for that. In PHP, for example you could use:

$isPrimaryColor = in_array($someColor, array('Red', 'White', 'Blue'));
