I agree with all of this.
A white card is more suitiable in darker conditions because it's less likely to exhibit noise, that noise sampled for WB will be less reliable.
But not this...With all due respect, no you can't, because white is so much closer to the limit of over-exposure.
Exactly... so it's not as easy to lose the data, as it requires so much more exposure.
Yes you can, but 127 is mid grey, so much harder to over expose. Everything I'm talking about here is regarding white balance. not exposure. The only reason I suggest using a grey card is because not only is the reflected light levels guaranteed (not important for white balance) but so is its neutrality, which IS important for white balance...
...Using a white object for white balance makes zero sense.
