Hello!
We’re sorry for the trouble you are having.
Concerning your question, please note the following:
1. The color of the toggle mobile menu by default is black.
2. The above steps should work out for you since they work on all of our sites.
Since they are not working out, then something else not related to the theme is conflicting with your CSS.
To debug the problem, you can try the following:
1. Deactivate temporary all plugins.
2. Clear the cache from your browser, server, and CDN.
3. Make sure to remove temporary any custom CSS codes that you have added manually to your website.
The above steps should logically solve your problem. The next step would be to identify the plugin that was the causing the issue. To find that out, you will need to re-activate your plugins one-by-one until you find the one that is causing the problem. Before every test, you have to make sure to clear the cache from the browser, server, and CDN — or deactivate all caching completely until you’re done with your debugging session.

Please note though that the problem you are experiencing is not related to our theme. The solution would mostly involve a third-party plugin that our team can not debug or fix since it would be beyond the range of our free support channel.
We hope that helps!
