Change color of hyperlink

hello, are you talking about changing selected ( highlighted ) text colors and backgrounds? if yes, add this code to your css file after you set your color and background :

::-moz-selection { /* Code for Firefox */
    color: red;
    background: black;
}

::selection {
    color: red;
    background: black;
}

if it does not work, add !important after the colors to force using this rather than the old code.

You may find the option to change the color of Links from your Dashboard >> Appearance >> “Theme Options” >> General Settings
