Change the color of mentorhelps from pink to something else

[Haine]

This is currently how mentorhelps are colored, for reference.  They were changed from blue and red since that is how adminhelps are colored and they blended together too easily.
I was under the impression that this color was decently readable, as people said it was when I was first testing different colors.  Let me know if this is no longer the case for most mentors, I guess.
