I try to visit Pirate 4x4 when I can to read about jeeps. The biggest problem is that the color scheme hurst my eyes after a while. So I found out about Greasemonkey for FireFox and you can write custom scripts to edit "stuff" on a website. So I found a quick piece of javascript code on a site for editing css and modified it for Pirate 4x4. So to install and use it here are the instructions
1) Install Greasemonkey for firefox.
2) Visit the script home for "New Pirate 4x4 Colors" and click install this script on the right.
3) Visit Pirate 4x4 forums and seee it change the colors.
Note:
So that you know when you load up the page it will load up the normal colors then once the page is done it will execute the Greasemonky script and change the colors.
Hope you find it useful.
