create implication gold_bikini -> yellow_bikini

Makes sense to keep a specific tag for the shiny kind of bikini, but it's still yellow.

The gold colors though are mixes yellows, oranges, and/or browns. It would probably be best to not force it to be defined as only a shade of yellow.

Yeah, I guess there's the issue of orange bikini.
