Abstract Three mechanisms have been suggested to account for the photometric variability in T Tauri stars: (1) changes in the effective photospheric spectral type; (2) changes in the optical thickness of the chromosphere; and (3) changes in the optical thickness of the dust shell. The author investigates these processes with color-color diagrams and energy distribution plots of 14 stars located in the Taurus-Auriga dark cloud complex. A relationship between a strong chromosphere and chromospheric variability was found as well as a similar relationship between a thick dust shell and dust shell variability. There is some evidence that the stellar photosphere becomes more stable with increasing age during the T Tauri phase.
