User email login and conditional access to course

I have the following issue and I am hoping someone can suggest possible ways of solving it:
In my Wordpress Learning Management System site which is using the WPLMS theme found on Themeforest
1. I want users to be able to login with email addresses
2. Depending on the login email address, it should change the colour scheme and the course.For example:
a. If user1 logs in with @google.com email, it should show google logo,its colour scheme and its courses
b. If user2 logs in with @amazon.com email, it should show amazon logo, its colour scheme and its courses.

Are there any plugins which can do this or any css / javascript code which can achieve this?

Thanks in advance.
