Help me.....
1. Upload your new colorset.
2. Enable it.
3. Disable "Colorset_Default" or whatever it's called
4. Restart the server.
If this doesn't work you'll probably have to do FTP to get it working:
1. Open the zip folder of your new colorset.
2. Find "colorset.txt"
3. FTP it to replace the other "colorset.txt" file (config/server/colorset.txt)
If you don't know what FTP is or how it works, there are some tutorials.
