Peach is a little bit orange, a little bit pink. A refreshing fruit smoothie on a hot summer day. Purple is the intersection of blue and red, and carries all the intellectual superiority of blue, with all the dangerous passion of red, making purple an arrogant elitist of the highest order.
Purple doesn’t like to share the spotlight, but Peach comes in as a friendly, unassuming friend, and promptly takes over, turning Purple into nothing but an accessory, as in the outfit above. Purple is, of course, aghast at first, but then realizes this is a chance to relax for a bit. She doesn’t always have to be in charge.
These two won’t spend a long time together though, because Purple can only be ignored for so long. She will come to resent Peach’s bubbly dominance, and push her to the side. Purple isn’t used to competition, she sees herself as a de facto winner. Peach is amused by this resentment and plays along for a while, pretending to be surprised, but eventually she will move on without putting up too much of a fight, because she’s got better things to do with her time, like spread joy wherever she goes. If Purple can’t appreciate that, it’s none of Peach’s concern.
