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 email, it should show google logo,its colour scheme and its courses
b. If user2 logs in with 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.
