Typically Crocs run small.  With the loop on the back these run very small so you lose almost a full size.  I bought the 8 black/red  on sale, but can't use the loops because it's like a 7.5.  As an 8 it is still a bit smallish but okay.  The bottom is pebbled which I don't like so I put in a full Dr Scholl's insole to solve that problem.  Great for around the house/yard though.  As for the "brightness" factor, I believe that's your own taste.  I like the hot pink accent personally.
