An agreed upon deltaE value (and a formula for that deltaE report). The
distance (difference) between two colors.
I don't believe there's much debate that a dE value far below dE of 1, as I
provided for the two sRGB values, are a far smaller color difference the human
eye can see.
There is some debate for good reason what values appear differently between two
colors.

And while I love the Chromix products, if you want a tool that really shows
this off well, visually and numerically, BableColor CT&A is the cat's meow.
