Need definitions of: Dark; Warm; and Bright


Throughout thousands of postings, the descriptive adjectives of dark, warm, and bright are employed.  What does each of them actually mean?  Are these meanings solely subjective, or can they be seen in displays of frequency responses and distortion across an audio spectrum?

@hide45, Robert Hartley? You pick strange people to be your gods.

There are people more qualified to comment on audio matters than an english major. 

As for my answer, it certainly qualifies as more of an answer than what came before it and it was very specific. If you had a bit more knowledge and some decent equipment you could make yourself qualified to make statements on those assertions, maybe your definition of bright is different than mine. Anyone here with the capability can make these frequency adjustments and see if they agree. Maybe they will not and we can talk about it and perhaps come up with better definitions. But you? Just hot air I'm afraid.
I have a question,not to hijack the OPs thread,but how did this thread take a nose dive right in to the ground?  
@rocray,  it’s far to common here that someone asks questions that may quite often have some legitimate answers to be offered but the trolling, sniping and self aggrandizing crew can’t help themselves.  Instead of scrolling along and keeping the snide remarks to themselves they bolster their post count with short, snarky or rude comments then head to the next sandbox to kick more sand or take a verbal dump in.  Bitter folks that should find another hobby or leave the forum if they truly believe everyone else is stupid and they are unquestionably correct about their assertions. 
Dark is when there is a an overly soft treble that causes no life to the very upper treble. Warm is when the entire balance is too bass centered which causes a lack of openness to your entire midrange and treble. Bright is when the sound is centered to the mids and highs too much which causes an overly bleached and thin sound.
I enjoy what @hilde45 has to say and typically what he has to offer.  Smart guy.

In my early days of business, just out of college, I was in hi-fi retail for a few years.  In order to help communicate the sonic signature for some of our customers we would use the terms "chocolate mid-range" and "butterscotch highs".  It seemed to convey the message nicely.  Ultimately it was the customers decision as to what sound they preferred and, hopefully, to make the purchase.  But the point is that words do matter and words are indeed for communication.
