1. Zakina would go with the Lilies of the Valley. That flower in particular represents friendship and the trust that comes with it, so a perfect fit for a crew that's been adventuring together for over a decade. Plus it sounds pretty to her and would invoke pleasant imagery when people heard it in stories that made their way around taverns everywhere.
Jordeira would opt for professionalism and go with the Ivory Talons. It isn't a mouthful and has a certain weight to it that's on par with reputable mercenary bands or organized crime syndicates. Not that Jordeira wants to be compared to criminals, but he can admit that their names are memorable and show that they mean business.
2. Kina's colors would be Mardi Gras purple, cotton candy pink, and robin egg blue. Pink for her playful nature and boundless curiosity, which tends to put her front and center in situations where she'd rather fade into the background. Purple for her intense emotions and creativity, which tend to lead her into bouts of introspection. And blue for the moments of calm and quiet that allow her to truly relax and let her guard down, even if it's brief.
Jordeira's colors would be dark moss green, metallic red, and antique white. Green for his determination and focus, which helps him push every job to completion, no matter the circumstances. Red for his volatile emotional state and violent outbursts, putting him at odds with everyone and leading him to feel isolated at times. White for the clarity his freedom has granted him, giving him a spark of hope that he struggled to find for so long.
