Cant change the members username color

Ok if you look here http://bdboard.forumotion.com/general-discussion-f14/eye-colour-t148.htm#2119

You will see that the members username is grey which is hard to use I was wondering can I change it and if so how

Hello TigTrivers,
By changing the text/link color, you will be changing member's username colors.

To guests {in topics},
The guests will view the text color for member's usernames.

For members {in topics}
They will see the link color for member's usernames.

To change the color, please go to your administration panel.

=>Display Tab
=>Pictures and Colors
=>Colors
=>Colors and text size

~Text Color
~Link Color

=> Change color => Save

You can also add members in colored {non-hidden} usergroups to change member's 'username' colors,

Or,you can add this css code into your css stylesheet.

Code:

a strong , strong a ,  a span strong {
color : red;
}

You can edit the code and change the color of red to a color you wish to use.

Owwww very helpful Master marc thank you very much for your help
