Okay, here is my green lighted cover and the red standard cover.
The first pic is in natural light and is the most accurate colour wise (on my monitor at least) the red may be a tad deeper, green spot on......
the second pic is with flash, so a little washed out colour wise and not as vivid as the first, but shows the detail of the covers more.
EDIT: oay, just checked on my desktop pc as I was using my netbook, on this one the second picture is more colour accurate, typical, really does depend on monitor settings.....
if the red in the pics looks deeper then that is probably the most accurate one then.
the red is a deep rich burgundy red, the green is brighter, but not in your face bright, more like a granny smith apple green
