Style Sheet question / Creating more link colors!

The only area I probably lack the most knowledge in for HTML is stylesheets, since I have no clue how to use them. Right now on Vbulletin it allows you to input a link color that will settle for all link colors on the forum. But I have area's on my new style that the link color doesn't blend so nicely into, and other areas that it does. So I need two link colors. I'm not sure how I would obtain this, but I know it has something to do with using stylesheets, I think..

I first tried doing this, expecting the color to change, as it did, but there is no added hover color:

<a href="http://www.lycos.com"><font color="#333333">Click me</font></a>

I need somehow for this to work but with a added mouseover hover color. I'm fairly sure this can be obtained by using stylesheets. If there is an easier way, such as maybe:

<a href="http://www.lycos.com" color="#ffffff" hovercolor="#456345">click me</a>

Ofcourse this example is incorrect, but if there is a way to obtain what I need using this method, let me know

Any help would be great, thnx.

Never mind, I just answered my own question! I recalled yaxay.com having two different link colors on their forumhomepage, one is white that says "register", and then the main one. So by viewing the source I found out it uses the "class" thingy, and some stylesheet ofcourse. ^_^
