Hi cimmerin,
You can edit the ua-front-end.css stylesheet present in wp-content/plugins/ultimate-auction/css/ua-front-end.css by searching the below classes and changing color respectively as below:
For product title :
.wdm-single-auction-title {color:}
Ending in:
.wdm-auction-ending-time {color:}
.wdm-single-auction-ending{color:}
Reserve price has not been met by any bid:
.wdm-single-auction-ending{color:}
Sorry, you can not bid on your own item:
.wdmua-loggedin-error {color:}
Auction Description Tab :
.auction-tab-container {
background-color: ...}
Auction Description Tab Title :
#auction-tab-titles li{
background-color: ... ;
color: ... ;
}
Auction Price :
.wdm_bidding_price {
color: ... ;
}
Bids Place Text Box :
input#wdm-bidder-bidval {
color: ... ;
}
If you edit the ua-front-end.css with above changes and still the changes are not reflected then you can mark the color, background-color properties as important to override the css applied by theme.
Ex: .wdm-single-auction-title {color: red !important;}
