Hello, thank you for contacting our service. I am sorry for the late reply.
I checked the picture you attached. A dark greenish spot is observed on the left side of her nose. It's hard to tell what this is from just a photo. However, it can be caused by bruising, a fungal infection of the skin, or lichen or discoloration. Does she hurt that part? If she feels pain, you need to take her to the vet. She doesn't need help from the vet right away if she does not feel pain, and it is fine to watch for a few days. I recommend washing with shampoo. Thank you.

It’s right below his eye in this photo it’s darker in real life but looks lighter in the photo
