hey if anyone wants to do this: use this code
<script>
var colors = ["#fff", '#000', '#f0f', '#0ff', '#00f', '#ff0', '#0f0']
window.laytheme.on("newpageshown", function(){
var ix = getRandomInt(0, colors.length);
var color = colors[ix];
jQuery('#grid, #custom-phone-grid, .cover-region-desktop, .cover-region-phone, #footer, #footer-custom-phone-grid').css('background-color', color);
});
// https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Math/random
// Returns a random integer between min (included) and max (excluded)
function getRandomInt(min, max) {
min = Math.ceil(min);
max = Math.floor(max);
return Math.floor(Math.random() * (max - min)) + min;
}
</script>
