Problem changing menu colors with bootstrap-less 3.3.7

I'm doing a site with HTML5 and bootstrap-less everything works normally but I needed to change some colors in the navbar menu and I know I can do it through variables.less inside this file I navigate to the menu part where I copy all the code related to the menu that I want to edit and paste into my file .less but it does not work I do not want to have to use !important to change the menu being that I know I can do this only by moving the variables in the less that comes in bootsrap this is the code less of the menu LESS:

@navbar-default-color:             #fff;
@navbar-default-bg:                #f8f8f8;
@navbar-default-border:            darken(@navbar-default-bg, 6.5%);

//* Navbar links*/
@navbar-default-link-color:                #fff;
@navbar-default-link-hover-color:          #fff;
@navbar-default-link-hover-bg:             transparent;
@navbar-default-link-active-color:         #fff;
@navbar-default-link-active-bg:            darken(@navbar-default-bg, 6.5%);
@navbar-default-link-disabled-color:       #fff;
@navbar-default-link-disabled-bg:          transparent;

/* Navbar brand label*/
@navbar-default-brand-color:               @navbar-default-link-color;
@navbar-default-brand-hover-color:         darken(@navbar-default-brand-color, 10%);
@navbar-default-brand-hover-bg:            transparent;

/* Navbar toggle*/
@navbar-default-toggle-hover-bg:           #fff;
@navbar-default-toggle-icon-bar-bg:        #fff;
@navbar-default-toggle-border-color:       #fff;

Even though I change the values it does not change on my site notice that I left everything white to test and my site does not change:
