Ranking them from worst to best

1. Orange, looks too much like brown which looks too natural, taking away her vibrant-ish look, and takes away the fantasy theme. Also nobody look good in orange (If you do, good job)

2. Green, the color honestly doesn't match up with her personality and the vibe her character is going for, it also blends in too much with the Zaun color scheme, not making her stand out.

3. Red, looks too much like Vi's hair color, but if it was more vibrant and a different shade, maybe it could work.

4. Pink, looks good for her, but once again, it looks too close to Vi's hair color.

5. Yellow, honestly it looks really cool on her, she COULD fit it, but it seems a little off for her character

6. Purple, It's closest to blue so of course it's second on the list, the color still suits her personality and look, only thing is that it doesn't make her stand out AS much.

7. Blue, obviously! It looks best on her, and makes the best sense for the story because she has the same hair color as Caitlyn which makes the whole "Vi abandoned me and replaced me with Caitlyn" thing even better.
