I am looking to change the color of the forum topics from the standard blue to the background skin color of my site. I was able to adjust the fount size but not the color.

Also would like to change the color and size of the individual
thread titles to the same color as the background skin. I have tried to adjust the font size for this section but was unable to do so.

Thanks

Since these are links, you'll need to adjust the "Special Properties" for the specific section and put in the color for the visited/unvisted/etc.

I can only assume you are talking about the hyper links?
So when you expand a property in the style editor there will be a Special Link Properties that will appear when you expand that you will have the options to change the colors for:
Unvisited Link
Visited Link
Active Link
Hover Link

By the way you will need to do it for each property you want to change.

This is what I see am I in the right location? Not sure what color each number is.

font-size: 10pt;
font-weight: bold;
color: #666666;
background: #EEEECC;
padding: 2px;

OK I got the font size correct just wont let me change the color.
The only codes I get are #666666 or #333333 and #000000,
I tried looking for the main site background color code because that is the color I would like my titles to be but cant find it. Even tried to change it using the color code listed above but nothing happens. What am I doing wrong?

That looks like the primary settings for the class. Under that box you should see a "Special Properties" link. If you click that it should expand so you can set the colors for the links.

When I expand the special Prop all the boxes are blank

That's where you'll need to put in the color for your links. You'd use something like:

color: #FF0000;

or

color: red;

Where do find all the color code options?
Something that tells me what color #FF000; is?

Here's one:
