The claim that Aryanne is a recolor is is being brought up on a regular basis by leftybronies. It is mostly an emotional claim that gets flung out when the offender has no better argument to present.
However, this claim factually wrong.
Pic related is the very first picture of Aryanne in a vector style that has been made shortly after the first Aryanne thread spring 2014. The Lineart is 100% genuine and was exclusive intended for Aryanne as a character, months before later vector artwork was ever made.
While it is true that in later times Vector Art has been repurposed for Aryanne, these picture are both the minority of total art submissions and were never published under the name or the Original creator of Aryanne.
