Comment (by sidati):

 Replying to [comment:2 westonruter],
 What i'm saying is the problem is in the PHP code not JS, cause when i
 comment the lines where the root variable returned where no value entered
 (null), it works for null value but also affect other customizer
 functions, i think the same function is used by other functions in a
 different ways O.o

 {{{
         /*if ( ! isset( $value ) )
                 return $root;
         else*/if ( empty( $keys ) ) // If there are no keys, we're
 replacing the root.
                 return $value;
 }}}

 I know its not good idea for others settings where it have to be a value
 but for the Color settings i believe we need to consider the empty
 (transparent) value.


 To demonstrate the problem, go the customizer and set a color (BG for e.g)
 and try to make it transparent by clearing or deleting the HEX color code,
 and you'll see that you're no more able to change it forever :(
