*sun damaged* worthington tan boots - Women's size 6.5

These boots are sooo cute but they have been damaged from sitting by a sunny window. The boots themselves arent damaged, just the color. One side is darker than the other. I'm not sure if there's a way to fix it besides putting it in the sun on the other side. There is also a stain pictured but it almost just looks like part of the boot. Smoke free pet friendly home.
