I didn't outright SAY the parents actually dyed their own baby's hair, but if you put any other sister in that spot Lucy was in, and assuming they all look like Lily during their infancy, there would be no telling who is sitting  between Lincoln and Luan in that photo. There is no reason why Lucy's hair wouldn't be its natural color, but the artists painted it black in her baby photo so we'd know it's her. Plus, in Back in Black when Lucy had taken the dye out of her hair, the shade of blonde was roughly the same as the twins.
