There is Doppler effect observable (i.e. "red-shifting" or "blue shifting") as entities move towards or away from one another at significant percentages of c.
Carl Sagan discussed what it might look like to travel very close to c in "Cosmos". The traveler would be viewed as highly red shifted when moving away from an observer and highly blue shifted when moving towards. The traveler would have a compressed field of vision (tunnel vision of sorts) due to their own light waves starting to pile up in front of them (similar to what happens with air as you approach the speed of sound).
I'll see if I can find a video of his brief explanation (it used an example of a guy on a scooter in the Italian countryside).
