Blue.
Objects that are moving away from you appear to be blue.
The opposite is red.
You confused the two.
Red shift refers to the red end of the visible light spectrum, and the infrared end of the radiation spectrum. Red waves are low energy waves, and the physics of an object moving away from you means longer wavelengths from your frame of reference. The longer wavelength means less energy, and that's why objects moving away from you is called a red shift.
Similar idea for a blue shift.
