Style changes

Hi all,

I hope people will read this; the forum seems a bit inactive.

I installed “the conference” theme yesterday and like it so far. However, the view schedule button is different than the Registration button. Is there a way to fine-tune this? I tried to open the files, but I needed help with the structure of WordPress. I used to program ten years ago :).

So couple things I want to fine-tune/customize.
– The schedule button, I want this the same as the “REGISTRATION”
– The green color I want to change, my logo is mainly blue and red, so want to use those colors on the website as well. I only can change the blue background. This might not be a “The Conference” thing. I’ve the feeling everything is green.
– I’d like that the “REGISTRATION” button is opening in new tab.
