 HI,
 When i set a color using color picker for background for example, it work,
 but if i clear the color using "clear" button or by deleting the color
 value the customizer keep the last color or get the default color where i
 want it to be transparent and because there's no HEX code for
 transparency, making a background transparent became impossible.

 I believe the problem is in :
 {{{
 Wp-includes/class-wp-customize-setting.php - line 440
 }}}

 When the value is "null", the multidimensional_replace() function return
 the original value which is the default value or the last value.
