It is the color of the light shift. either red or blue, from an object, not the object itself, that determines if it is moving away( RED) from us or moving toward us (BLUE).
When the wavelength decreases, that's known as a "blue shift", becausethe color of any visible light shifts toward the blue end of the spectrum.That phenomenon is associated with a light source that's moving TOWARDthe observer.
The apparent color of the object.
The colour an object appears to be is the colour of the light it is reflecting.
Many objects observed in the universe show a red shift. It is believed that this red shift is caused by a Doppler effect - that is, that the objects are moving away from us at a significant fraction of the speed of light. If this is true, then it is evidence for an expanding universe.
The Answer is color. Because color has to do with light and physical properties.

no
No. If the object absorbs that color, then there's none left to travelfrom there to your eyes, is there !The color you see is the light that the object couldn'tabsorb, so itbounced from the object to your eyes.
True, color is just the light that an object is reflecting.
The apparent color of the object.

The object reflects all the incident light.

What we perceive as color is electromagnetic radiation. As objects heat up, the frequency of the energy they radiate shifts and broadens which means that the color changes. The actual color is dependent on, among other things, the frequency of the vibration of the bonds in the molecules, so different things look different colors at the same temperatures. The rate at which heat radiates from an object is proportional to the 4th power of the absolute temperature, so if you double the temperature, you get 16 times the rate of radiated heat. The rate at which an object absorbs heat is also dependent on its color. A "black object" is one that absorbs all radiated energy that hits it.
The way the light is reflecting off of the object shows the color that is not on the object
