how to return visited links into un-visited when refresh

[markii.borabon]

I got a simple problem here. what I want is when I recieve message from the user the links must be color blue, then if I read it it must change into a color red, then when they reply again, there message must turn into un-visited again or the message must turn to color blue.

its like...

if(message == read){

            color: red;
}else{ color: blue}

the basic logic must be like this..

please help.

Following your pseudo logic, closest answer would be

if (refreshed == TRUE)
{
    revertColor(red)
}
