Some gears change their detail colors when applying dyes.
Just dye the Sunset body and legging, take a closer look to the details and you will know what I mean.
The original: note the gold details at the sleeves

Dyed with any color will turn the details into silver one. Noted that these details have fixed silver colors regard less of dyes.

This happens with some other gears too.
Personally, I think some gear have cool gold/bronze details, but look less impressive in silver details, so you have to choose between default color (which you may not like) to go with other bronze/gold-detail pieces, or have to find other glam that looks good with silver details.
