The first time I got into trouble on BF, it was because I yanked the chain of a particular new and inexperienced member who immediately took it upon himself to “verify” so many of the things I said, sometimes leading members down a blind alley. So, I hope no one thinks I’m trying to pull that on Looksharp65. His words need no verification. I only speak to echo. (the caps are mine)
“The residual reflection is chosen TO SATISFY THE CUSTOMER'S NEED to see they really paid for something visible.”
This is like the original* (1933) Windex having a couple of drops of Aquatint to show homemakers they were buying something more than water.
“... common-sense tells that with a 99% transmission, a residual reflection of a very narrow wavelength span can't possibly affect the perceived colour balance THROUGH the lens.”
Also, AR coatings don’t have a color; they reflect a wavelength that is intuitively seen as color. Thus, the art of stacking BBs continues to grow.

* PS Today’s Windex formula specified as the "original" ... isn’t.
