zenjael ~ Something cannot be both itself and not itself at the same time.
Aristotle ~ LNC: Nothing can be both the case and not the case in the same way at the same time.
Postmodern Beatnik ~ People having different observations fails to violate LNC due to the "in the same way" clause. As Banno noted, two people having different experiences says nothing about what color the object actually is.
This is an important theme in Plato's Parmenides. It is Plato's objection to Zeno that is reflected by Aristotle as the LNC.
There are two distinct types of relativism: (1) subjective, which is relative to the observer, and (2) objective, which is relative to place, time, and relation.
It is the second type that concerned Plato. Zeno argued that nothing can be both like and unlike. This premise fails to relativistic objections. From different perspectives, or over time, or in varying relations (such as in comparison to smaller or bigger things) things are indeed both like and unlike in different respects.
Objective relativity is a major theme of modern science, which has been concerned to some extent with the laws of flux, change, motion rather than the laws of a static world. The laws of motion have been resolved by Galilean and Einsteinian relativistic theories (actually invariance of scientific laws under relativistic conditions).
