A black shirt reflects very little light, absorbing most of it and appearing black to the human eye. A white shirt reflects most of the light that hits it, appearing white.
white and something else
A white t-shirt absorbs all colors of light equally, reflecting them back to our eyes and making the shirt appear white. It does not absorb any specific color but reflects a combination of all colors.
