Theme Aurora. I need help with customizing.

Hello all.

I uploaded the Theme Aurora and I am having troubles finding the right code to edit.

I did a wp blog before but it was a year ago and don’t remember it being this hard to find even though I do not know jack about PHP and CSS.

I am trying to find where I can eliminate the blog title and I also want to change some of the font colors.

The green is just not to my liking so I want to change it.
The colors to be changed will affect all the titles in my sidebar and the titles of posts.
I thought I found the right colors to change but after I changed them no colors were changed on my blog. Even after 3 refreshes.

I eliminated the “another wp blog’ No problem but can’t find the blog title to get rid of it.

thanks in advance for any help you can give.
