Recently received an oak Bayswater, bought directly from the Mulberry store. The leather has a more butterscotch/orange color than the oak Bayswater in the image on the Mulberry site -- in that picture the oak looks more tan / less orange. The images on Net a Porter also look more tan, less orange. Yet there are many pictures of Oak bags on eBay and they all seem to look more the butterscotch color. It is rather confusing. Are the images at the Mulberry site less "orange" than the Oak leather IRL? Does the oak change in hue as it ages?
