Okay , so here's the problem
I've been thinking of having a winter theme for my forum , but here's the thing.
https://2img.net/h/oi54.tinypic.com/2n1fktt.jpg (Normal Look of Category Header)
https://2img.net/h/oi43.tinypic.com/2w1w8yu.jpg (Winter Look of Category Header)
I tested the winter look of category header in my test forum and this was the result.

I made 2 points in the image so that it's easier to understand.
1. How do I change the colour of the lines?
2. How do I change the background colour?

I really need help lol , I was supposed to do the winter theme around december , but cause of my exams and stuffs , I couldn't do it , so help pleeease

So you want to get rid of the purple lines and BG on this forum http://www.art-castle.biz/ ?

You'll change the color of the border here;

.pun table.table {
-moz-border-bottom-colors: none;
-moz-border-image: none;
-moz-border-left-colors: none;
-moz-border-right-colors: none;
-moz-border-top-colors: none;
background: none repeat scroll 0 0 #F1EFF1;
border-collapse: separate;
border-color: -moz-use-text-color #9400DE #9400DE;

And here:

#pun-info {
background: none repeat scroll 0 0 #F1EFF1;
border: 2px solid #9400DE

And here:

#onlinelist .right {
-moz-border-bottom-colors: none;
-moz-border-image: none;
-moz-border-left-colors: none;
-moz-border-right-colors: none;
-moz-border-top-colors: none;
background: url("http://cdn.iconfinder.net/data/icons/Siena/32/globe%20red.png") no-repeat scroll left center #F4F4F4;
border-color: #9400DE -moz-use-text-color #9400DE #9400DE;

As for the body BG:

body {
background-color: #803F77;
background-image: url("https://2img.net/h/i678.photobucket.com/albums/vv145/fred_100_the_gr8/gradient2.png");
background-position: center top;

Thanks , I'll give it a try and see if it works.
