Is deception involving artificially darkening a slave's hair a valid ground for rescinding the sale?

Primary text
The option to rescind the sale is valid because darkening the hair constitutes deception regarding something that affects the price. This action is analogous to darkening the fingertips of a male slave if the intent of fraud is established.

The perceived deception from darkening a slave's fingertips is not sufficient to void the sale because it is not exclusive to indicating scribal ability; it might result from accidental contact with ink or merely being a young attendant to a scribe. This level of mere conjecture does not justify rescission.
