That is because TeX doesn't like blah blah blah. If you type  
mathematics instead ...

  Actually the behavior, at least with TeXShop 2.26, is a bit more  
complicated:

If you place say twenty lines of text before % blah blah blah, the  
behavior is as you describe but if you do the same in a smaller  
window so that there is a scroll bar the behavior is correct. Also,  
if you do it in a big window and then change the window the slightest  
little bit, blah blah blah will get black.


This seems to be related to the fact that when you make a find and  
replace, the comments in the affected part turn black but revert to  
red as soon as you change the window the slightest little bit.
