Is there any absolute distinction between what is true and false?

This thread has reminded me of one of my favorite quotes.

"There are trivial truths and the great truths. The opposite of a trivial truth is plainly false. The opposite of a great truth is also true."
Niels Bohr

It's nice to see the colour example done correctly. So many people use colour as an example of pure subjectivity and forget that colour is defined by wavelength and can therefore exist objectively, even though we don't perceive it that way.
