Create Web Safe Color palette using JavaScript

<script language="javascript">

//first lets start with the table that will contain the palette
t='<table width="50%">';

//next we define the array of basic colors including black, white and gray
c=new Array('00','CC','33','66','99','FF');

//now we will iterate through colors. Notice how number 6 corresponds to number of items in the array c
for(i=0;i<6;i++){
 for(j=0;j<6;j++){

 // each row will have 6 colors
  t +='<tr>';
   for(k=0;k<6;k++){

    //this creates hex code for each color
    l=c[i]+c[j]+c[k];

    //now lets create table cell for each color
    t+='<td bgcolor=#'+l+'>#'+l+'</td>';
   }
  t +='</tr>';
 }
}

//now let's display the palette 
document.write(t+'</table>');
</script>
