@bromontana8 fluorescent lights will turn pink (caused by a loss of mercury) with black burns on the ends of the lamp as the light reaches its end of life. The voltage going through the tube will cause the tube to breakdown sooner. Since you already changed the lights you may have to check the ballast. Last but not least you muse consider that you maybe not using the correct tube for the fixture. Double check on that.
