<human>: My girlfriend has seven tattoos. A couple are symbols, others are illustrations of objects, all related to a topic she studied in college. They are well done tattoos, but they are all black ink and skin. No color at all. Her explanation was that it started unintentionally but she embraced it as an aesthetic choice going forward. In reality, it makes her look covered in half finished tattoos. Only a small bit of color would improve so many of them. And now she's telling me she's going to save up for another tattoo! When I asked her about color, she said no. I just wish she could be more open minded. We have many tattoo artists and inked friends in our social circle. Should I suggest one of them to talk to her about this? I'm not the first one to think her tattoos look unfinished.

Can you summarize the given text in a few sentences?
<bot>: How do I encourage my girlfriend to fix her tattoos, or at least get her to get better tattoos in the future?
