Selection is easy:

/*colorize text selection */

::-moz-selection { /* Firefox */  color: #ffffff;
background: #4700ff;    }

::selection {color: #ffffff;
background: #4700ff;    }

Dunno about the mobile chrome panel though. Would love to hear an answer to that as well!

edit: obviously have to go to any custom code field - in settings or on the page settings or in embed. I perefer site settings since it works for the whole site
