First, the best way is to use jQuery:
<script src="http://code.jquery.com/jquery-latest.min.js" type="text/javascript"></script>
You are using checkboxes while in your case it's better to use radio buttons (as David Thomas said).
To distinguish between clock color radio group and arrows color radio group, you have to use a name attribute for each group along with a CSS class. So the html would look something like this:
<div class="demo2">
<div class="tag">Clocks color</div>
<input type="radio" id="checkbox-1" name="clock-color" class="regular-checkbox big-checkbox color1 clock-color" /><label for="checkbox-1" style="
background-color: #eeeeee;" ></label>
<input type="radio" id="checkbox-2" name="clock-color" class="regular-checkbox big-checkbox 2color clock-color" /><label for="checkbox-2" style="
background-color: #4b69af;"></label>
<input type="radio" id="checkbox-3" name="clock-color" class="regular-checkbox big-checkbox 3color clock-color" /><label for="checkbox-3" style="
background-color: #403486;"></label>
<input type="radio" id="checkbox-4" name="clock-color" class="regular-checkbox big-checkbox 4color clock-color" /><label for="checkbox-4" style="
background-color: #3ea03b;"></label>
<input type="radio" id="checkbox-5" name="clock-color" class="regular-checkbox big-checkbox 5color clock-color" /><label for="checkbox-5" style="
background-color: #f0df0d;"></label>
<input type="radio" id="checkbox-6" name="clock-color" class="regular-checkbox big-checkbox 6color clock-color" /><label for="checkbox-6" style="
background-color: #f5a02c;"></label>
<input type="radio" id="checkbox-7" name="clock-color" class="regular-checkbox big-checkbox 7color clock-color" /><label for="checkbox-7" style="
background-color: #d23f2d;"></label>
<input type="radio" id="checkbox-8" name="clock-color" class="regular-checkbox big-checkbox 8color clock-color" /><label for="checkbox-8" style="
background-color: #201b21;"></label>
<div>Arrows color</div>
<input type="radio" id="checkbox-1-2" name="arrows-color" class="regular-checkbox big-checkbox 1color arrows-color" /><label for="checkbox-1-2" style="
background-color: #eeeeee;"></label>
<input type="radio" id="checkbox-2-2" name="arrows-color" class="regular-checkbox big-checkbox 2color arrows-color" /><label for="checkbox-2-2" style="
background-color: #4b69af;"></label>
<input type="radio" id="checkbox-3-2" name="arrows-color" class="regular-checkbox big-checkbox 3color arrows-color" /><label for="checkbox-3-2" style="
background-color: #403486;"></label>
<input type="radio" id="checkbox-4-2" name="arrows-color" class="regular-checkbox big-checkbox 4color arrows-color" /><label for="checkbox-4-2" style="
background-color: #3ea03b;"></label>
<input type="radio" id="checkbox-5-2" name="arrows-color" class="regular-checkbox big-checkbox 5color arrows-color" /><label for="checkbox-5-2" style="
background-color: #f0df0d;"></label>
<input type="radio" id="checkbox-6-2" name="arrows-color" class="regular-checkbox big-checkbox 6color arrows-color" /><label for="checkbox-6-2" style="
background-color: #f5a02c;"></label>
<input type="radio" id="checkbox-7-2" name="arrows-color" class="regular-checkbox big-checkbox 7color arrows-color" /><label for="checkbox-7-2" style="
background-color: #d23f2d;"></label>
<input type="radio" id="checkbox-8-2" name="arrows-color" class="regular-checkbox big-checkbox 8color arrows-color" /><label for="checkbox-8-2" style="
background-color: #201b21;"></label>
</div>
Next, in your SVG you have to use IDs for your paths:
<path id="clock" .../>
<path id="arrows" .../>
Finally, this script should do the trick:
<script type="text/javascript">
function hexc(colorval) {
var parts = colorval.match(/^rgb\((\d+),\s*(\d+),\s*(\d+)\)$/);
var color = '#';
for (var i = 1; i <= 3; i++) {
parts[i] = parseInt(parts[i]).toString(16);
if (parts[i].length == 1) parts[i] = '0' + parts[i];
color += parts[i];
}
return color;
}
$(document).ready(function () {
$(".clock-color").click(function(){
chkID = $(this).attr('id');
color = $('#'+chkID).next('label').css('backgroundColor');
color = hexc(color);
$("#clock").attr('fill',color);
});
$(".arrows-color").click(function(){
chkID = $(this).attr('id');
color = $('#'+chkID).next('label').css('backgroundColor');
color = hexc(color);
$("#arrows").attr('fill',color);
});
});
</script>
