Reason for the faint math expressions (not text!) is that these expression were not evaluated before the file was last saved.
Auto-Calculation in the file is turned off.
Turn it on and the expressions will be evaluated:
But because some of the variables used in the assignments are not defined (in case of µ not in front or to the left of the assignment), you get the red errors.
I guess that these math regions were not meant to be calculations to be evaluated but rather equations shown just for reference. In this case you should not use the assignment operator (:=) but rather the boolean equal (comparison equal, the 'fat' =)

You can turn off redefinitions warning altogether or just select that it should not be triggered for variables, etc.
