Need some with a good eye.

I have a website with primarly black and silver theme and I'm wondering what to change this stuff to:

Page Background Color
Format - #FFFFFF

Table Width
You may use either exact pixels (recommended: 600) or a percentage (recommended: 95%)
Font Face (e.g., Verdana)
You may use a backup font as well. For example: to use Verdana as your first choice, with Arial as a conditional font for those users that don't have Verdana as a font on their system, you would type "Verdana, Arial") Font
Link Color
Guestbook link color. Format - #FFFFFF

Text Color
Guestbook text color. Format - #FFFFFF

Text Size 1
The text font size. Text Size 1
Text Size 2
A smaller value is recommend here ... but depending on your font face, you may want to alter this. Text Size 2
Table Header Background Color
Format - #FFFFFF

Table Background Color
Format - #FFFFFF

Table Header Strip Text Color
Format - #FFFFFF

First Alternating Table Column Color
Format - #FFFFFF

Second Alternating Table Column Color
Format - #FFFFFF

Something to match this http://sobaids.com/phpBB/

Here's a link to a page with websafe colors and their corresponding numbers:

As you can see, here are some numbers for:

Silver CCCCCC

Silver 008000

Gray 808080

Dark Gray 666666

Black 000000

You just have to try some color combinations and see how they look.

Thanks for the help. Got a good scheme excpet the guestbook text in the upper left corner looks cheesy. It's gray colored on top of a black background. But other than that it looks nicer than it did before.

That is actually a picture and not text. You should replace it with your own picture or customize your header to match the rest of your site. Same thing with the red "sign the guestbook". It looks bad and should be replaced with a different picture.
