Hey Robert,
Do us a favour and do some of the work yourself, OK?
I'm rushed off my feet and have no time to answer every one of your nit-picky stupid-assumption questions.
Learn how stuff works, and spend your time answering questions - we'd all appreciate it.
As a hint, the answers to all your questions in this post are embedded in the issues of colour hue, colour saturation, image brilliance, and contrast. It may surprise you, but these four parameters are NOT completely independent.
In fact, there are only about 2.5 degrees of freedom in colour space. Trying to play games with four variables leads you into trouble which simplistic notions don't explain.
Rather similar, IMHO, to postulating liquid water when the mean daily temperature is -40 C...
