I am not sure what you mean by "turning dark".  Do you mean that they are dusky (bluish)?  This could mean there is an issue with her circulation.  Or do you mean that the skin is darker (more pigmented)?  Sometimes medications, changes as we age, or sun exposure can do this.  There is no mention of a rash or other symptoms, such as itching or pain, in your question.  If you are really concerned, you can have it checked out by a dermatologist.
