Can anyone explain this behavior?
Create a black (0,0,0) object and a white (255,255,255) one in a document, each in its own layer with the black one directly on top. Set the top layer to color burn. If the blend color is 0,0,0 and the base color is 255,255,255, shouldn’t the result be darker than the base color? But no, the result remains 255,255,255. White is indeed the neutral color for color burn but the nuetral color must be in the blend color NOT the base color to give this kind of result.
The kicker is that if you replicate the above steps but change the base color to 254,254,254 the result is indeed darker. I admit no sane person would worry about this, but it drives me batty. Am I missing something obvious?

From the help file:

"Looks at the color information in each channel and darkens the base color to reflect the blend color by increasing the contrast. Blending with white produces no change"
