Try this. put it in the custom css in the admin panel. Made a post edit. Forgot to add the semi colon after the color.

.ow_footer_menu a{
color: your color;
}

Paul, have you managed to fix your issue?

No, thanx for the effort Darryl, but still the same color..

What is your theme? The above would work on simplicity. I found that on my Venus theme it is
.ow_footer a{
    color:your color;
}
instead of .ow_footer_menu a{
I checked a few other themes that I have one is div.ow_footer_menu a{
The way I find this is by using Inspect Element.
1. right click on the item you want to look at.
2. choose inspect element from the pop up menu.
3. usually the code from the area that you clicked will be highlighted. The corresponding css is in a box to the right.
4. You can click the select arrow to the left of the inspect element header box; then select any element on the page to make sure you are displaying the right one.
5. You are most likely looking for a variant of one of the above that I have found.

The cool thing about inspect element is that you can try css changes without them being permanent.

p.s. If you had a website link, where I could see your footer, I could get you the exact code to change.

Based on the screen shot. It looks like you are using the Darklets theme. If that is the case, it would be this.

.ow_footer a {    color: #0091a9;}
This is what I found with Inspect Element. I changed the color to make sure it was the correct element
