Being out in the sun with it will really make it patina quickly. My delightful is 2 years old and I used to sit it out on the balcony or by the door with the blinds open to help it tan. Mine is slightly darker than yours. Just think of it this way, it's just doing what it's supposed to do, vachetta will darken. I love the way my bag look because there are no marks or stains on my leather.
