A red shirt under a red light appears pale because red
reflects nearly all light falling on it
Unable to reflect lights falling on it
absorbs all lights falling on it
absorbs other colours and reflects red
Explication
Under red light, the shirt reflects the red light but does not reflect other colors, which makes it look less vibrant or pale, compared to being illuminated by white light that contains all colors.
