Colours can be specified by their rgb values (red, green, blue).
Don't put a space between the "rgb" and the "(" or it will not work properly.
This page was made to look this way by putting the following between the <head> and </head> tags:
<style type="text/css">
body { color: rgb( 20, 20, 250 ) ; background: rgb( 255, 204, 204 ) ; }
</style>
