Can you give me CSS code to replace Login button colors if they are hard-coded to the template?

I think that the color for the "Register for an Account Today" and the "Login" buttons on the Login page are hard coded into the template as they do not seem to be following my primary and secondary colors.

If this is true, can you please give me a snippet of css to change the color of those two buttons on that page.

If the buttons are getting their colors from the template please point me in the right direction. I have been through all my colors multiple times and am not finding that #6A6AD9 color.

Thank you for everything. I am SO looking forward to launching our site with this new template.
