How to change the color on custom radio button?

[csKangGdcomm]

Hello!

I want to change the color in the checked radio box.

Current color is blue like below.

I found the issue that seems related twbs/bootstrap#20118

A version what I use is 3.4.1. and there is no _custom.scss file in the library and

I fail to change the color.

Below code failed as well ( change the default color ).

Can you give me some advice?

$brand-primary: $color-point;
$brand-info: $color-point;
$input-border-focus: $color-point;
$state-info-text: $color-point;
$btn-default-color: $color-point;
$btn-default-bg: $color-point;
$btn-default-border: $color-point;
$btn-primary-color: $color-point;
$btn-primary-bg: $color-point;
$btn-primary-border: $color-point;
