The colours are beautiful, in my opinion the blues are more of a light and dark denim and the accent is a mustard yellow.  It is more than long enough on a king size bed but the width could be a bit wider. It fits but not much hangover. You could turn it the other way but then the pattern would be running in the wrong direction.
My husband loves how light it feels and it is very soft to the touch. The price was amazing for the quality!
