Go to ACP - templates and styles. Click on themes - Selenium. Then click on the custom.css stylesheet.
Find this (line 37):
thead.main {
background: #e74c3c;
font-size: 11px;
color: #fff;
}
Then replace #e74c3c with the colour of your choice. This site might help with picking colours:

Right click on one of them and select 'Inspect element' or 'Inspect'. That will show the stylesheet element you need to find and change. For example, if I right click on your user name I can see that I would need to look in global.min.css for a:visited and a: to change the colour.
