Is there a way to...

Make open dental recognize the age of procedures and change their color in the patient chart? (e.g. a new filling would be blue, but turn gray when more than 2 years old)

Not at this time. Feature request. Check out request #1559 and #1779.
Currently, the color only changes based on the entry status ie; tx proc will be blue and once set complete will turn green.
