Changing colour of group, in a readymade skin.

I have solved this problem.. It is taking me a little time to get use the admin panel
Please bare with me !


I am using the English Gothic skin..
I ahve worked out how to create a new group and choose the colour of their user name..
But this skin had two existing groups Admin and Moderator..
Admin is white and Moderator is Dark Blue..
My eyes are what they use to be and the Blue is really hard to see on the dark background...
I have no idea how to change this colour.. I have clicked on everything that i think may help , to leading me to here , hoping to get some help..
I looked in frequently asked questions and have found out what i already knew, it doesnt tell you how to change the colours on the already formed groups.. only how to choose the colours for the newly formed groups. the same technique is not applying for some reason.


As you can see i am new..
Can someone please help me out here..Please!!
