[html] Change hover color on a button with Bootstrap customization

I am trying to style my buttons in a way that the hover makes the button a lighter shade instead of a darker shade. I tried bootstrap customization page(http://getbootstrap.com/customize/) and it doesn't give me an option to change the button hover color. I tried doing this manually by inspecting the CSS but it is unclear how the buttons are getting the hover color. I tried another bootstrap customization website

http://pikock.github.io/bootstrap-magic/app/#!/editor

I wanted the main color to be #0495c9 and the hover color to be #00b3db but I am only able to specify the button bg color and not it's hover color.

Any help will be appreciated

or can do this...
set all btn ( class name like : .btn- + $theme-colors: map-merge ) styles at one time :

@each $color, $value in $theme-colors {
  .btn-#{$color} {
    @include button-variant($value, $value,
    // modify
    $hover-background: lighten($value, 7.5%),
    $hover-border: lighten($value, 10%),
    $active-background: lighten($value, 10%),
    $active-border: lighten($value, 12.5%)
    // /modify
    );
  }
}

// code from "node_modules/bootstrap/scss/_buttons.scss"

should add into your customization scss file.

This is the correct way to change btn color.

 .btn-primary:not(:disabled):not(.disabled).active, 
    .btn-primary:not(:disabled):not(.disabled):active, 
    .show>.btn-primary.dropdown-toggle{
        color: #fff;
        background-color: #F7B432;
        border-color: #F7B432;
    }

I had to add !important to get it to work. I also made my own class button-primary-override.

.button-primary-override:hover, 
.button-primary-override:active,
.button-primary-override:focus,
.button-primary-override:visited{
    background-color: #42A5F5 !important;
    border-color: #42A5F5 !important;
    background-image: none !important;
    border: 0 !important;
}
