Unless it's just my phone.

The page list bar at the bottom of each page doesn't seem to have a colour change indication to show what page you are on when browsing multiple pages in the market. 

For example when on page 8, the number 8 could be boldened or the box be a darker colour.

Yes, I agree. I had the same problem. It's hard to tell which page we are on. The box should be marked with something, or the simple way is, just like you said, to change the color of the box number.
