I used the same center for all 4 and they only used light blue, so I was OK.

Yes, I understand why they use colored paper.  And I understand why the color gets changed between different centers and without notice.  That's just a smart security practice.

BUT - isn't there someplace we can complain to about the unreadable dark and fluorescent colors??  Surely there are SOME quality control standards for testing center materials!

Maybe I'm asking too much.  I'd also like to get a mousepad with a backing that doesn't slide all over the desk.  Mousepads cost $5; you'd think the center could afford to have a decent mousepad at every station.  And I'd like to see the test proctor swab the soundproof headsets with alcohol between each use.  Alcohol swatches cost almost nothing.  But those things didn't happen either.
