I found the answer to my own question and posting the solution here for anyone that runs into the same problem
I was able to change the color for my Login and Create Account links on the main page of the Comstock template by going to Includes>Languages>English>Comstock>Index.php (you may substitute the name of your template instead of Comstock if the code is the same in your template).
Then, on the first paragraph of the Index.php file you will see:
define('TEXT_MAIN','');
if (STORE_STATUS == '0') {
define('TEXT_GREETING_GUEST', '<span class="greeUser"></span> <a href="%s"style="color: #009999">Create Account</a> <span class="greetUser"></span><a href="http://YourWebsiteName.com/index.php?main_page=login"style="color: #FF0000">Log In</a>');
You need to add the html code in bold with your appropriate color. In my case the red color for Login is represented by #FF0000. You may want to checkout a free list of color codes on the web for your color of choice (called hexadecimal since it has six numbers and letters). Also notice, you need to include your website's URL after the http:// I hope this helps.
