Yeah . . . right! So that prompts a question. Why is the red off if I correctly used the BTN approach (an assumption, I know)? Like I said . . . deceptively simple but does not necessarily deliver a correct result

It may have something to do with the highlight choice for the reference point, Your Alt-Click sample. How big is your sample size in the Config area ? If you are set to 3 X 3 pixels try the highlight again at 5X5 just to see if the sample is messing with you.
Example, if the sample size is 3X3 you get the average of 9 pixels. If for some reason the majority of the pixels you chose are blue the correction might result in a yellow cast in the highlights. 5X5 giving you 25 pixels for the sample may even this out.
