Change box color for Cookie Script

I want to change the “Got it!” box color in this cookie script. I have changed all other colors.
I think the color is in the.js
Is there css code I can add to change that yellow box to another color?
By the way this is Blogger.

   <script type="text/javascript" id="cookieinfo"
src="//cookieinfoscript.com/js/cookieinfo.min.js"
data-bg="#645862"
data-fg="#FFFFFF"
data-link="#F1D600"
data-cookie="CookieInfoScript"
data-text-align="left"
   data-close-text="Got it!">
   </script>
