I have found the solution…
Firstly, My apologies it was nothing to do with UM

Secondly, I found this article that pointed me in the correct direction
https://docs.ultimatemember.com/article/151-how-to-hide-the-page-title-on-the-user-profile-page

I therefore “Inspected” the specific page element that was the white link and found that the Colour FFFFF (being White) is used…

Then I followed this article to know how to change it
https://ww.wp.xz.cn/support/topic/ultimate-member-text-color-change/page/2/#post-14711005

and in my Custom CSS I pasted the below

.pagelayer-body a{
	color:#efba6cff !important;}
.pagelayer-body a:hover{
	color:#2196F3 !important;
}
.pagelayer-wp-menu-container .sub-menu a {
    background-color: #767676;
}
