Theme Custimization Help.

[ninja111]

Hello,

I need help customizing Smf Default Theme Curve.
I want to change the blue colors to red.
I have gone into Admin> Themes And layout> Modify Themes> Edit this theme's StyleSheet> index.css.
After that i get to:

   background: #E9EEF2 url(../images/theme/backdrop.png) repeat-x;
   font: 78%/130% "Verdana", "Arial", "Helvetica", sans-serif;
   margin: 0 auto;
   padding: 15px 0;

I can edit and change that, but you can still give me a few tips if you fell you should.

It's the colored titles that i'm having a problem with. I can't find where to edit them.
Can you help please.

To change that part is a picture called main_block.png
to change the color you just have to edit the image using Photoshop
