Donīt forget that colors are also a "learnt behaviour". We learn how to define red at school, and thus we are "fed" the standard ideals of that, and later on we have to ask our selfes how to define color because it is mainly to your own mind you can refer. Orange and red are soewhat hard to tell if it choosen to be called red or orange at some state. We donīt go around and refer to colors using the CMYK print labels (well sometimes

but that is in work since you have to..)
Truth is mainly to your own ideals and decoded by your own perception and memory, thus there are maybe one truth, as a higher state, but then there are as mny shades to the truth as there are persons knowing about it.
it is a tough topic here Yorick (I didnīt expect less from you! You really tease the brains mate!!)
