Thank you again bagginsbill; I could not have expected a better answer!  These calculations are exactly what it is I need to understand!  And I'm very grateful you took the time to lay this out, for me, so well!

This is why I'm an artist, Mmn..literally!  In my mind mathematics ans science are a must; but in my eyes, there is a cry for translation.  I'd very much like to view and understand this with much more fluff; so the next person will have an easier time grasping the concept as well!  This is the kind of thing I'd like to print out and just oogle at, on my while, because it just looks so complicated; so when I do'nt get it I can just be happy I'm not going to get tested on it!

"It is a negative color!!!!"*

That is what I thought.

Why is it that values of 2(for Value_1,) and 1(for Value_2) cause more of a dissplacement than values of 1, and .5(if you hav'nt already answered that a couple times over?)
 

 

 

Seriously, 1000 thanks!
