I have added code snippet to my team site containing the following code:-
<div class="ms-comm-adminLinks ms-core-defaultFont ms-noList" unselectable="on">
<div class="ms-webpart-titleText" unselectable="on"> Useful Links </div>
<ul class="ms-comm-adminLinksList" unselectable="on">
<ul unselectable="on">
<li class="ms-comm-adminLinksListItem" unselectable="on"><a href="https://login.salesforce.com/" target="_blank" unselectable="on"> Salesforce </a></li>
//code goes here
</ul>
</ul></div>
but this will have the defualt light-grey back ground color as shown below. so is there a way to modify this background color without affecting the ms-comm-adminLinks ms-core-defaultFont ms-noList format ?

EDIT
I have added the following to my custom CSS file:-
.ms-comm-adminLinks {
background-color:#008CD2 !important;
}
.ms-comm-adminLinksListItem a{
color:white;
}
.ms-webpart-titleText{
color:white !important;
}
And it chnage the format as needed, so is this approach wrong or considered risky, and the result is now as follow:-
