Example 2
Display an alternate background color for 8 bit screens (to avoid that 8 bit screens, which do not support the modern color, uses an ugly substitute color instead):

//simple blue background color for 8 bit screens
document.body.style.background="#0000FF"
else
//fancy blue background color for modern screens
document.body.style.background="#87CEFA"
</script>
if (screen.colorDepth<=8)
//simple blue background color for 8 bit screens
document.body.style.background="#0000FF"
else
//fancy blue background color for modern screens
document.body.style.background="#87CEFA"
</script>
